1. A diffuser for a turbine engine, including an annular casing to seal compressor discharge air and struts attached to the casing to delimit an annular array of intra-strut regions, the diffuser comprising: a ring portion, including a ring shaped annular body with a forward face disposed on a forward facing side thereof and an aft face disposed on an aft facing side thereof, the forward and aft facing sides opposing one another and the ring portion being supportable by an integral connection between one or more of the struts and the aft face; anda splitter portion, including a ring shaped annular body with an aft face disposed on an aft side thereof to mate with the forward face of the ring portion body, the splitter portion further including:a lead edge, on a forward side of the splitter portion body, which is extendable into a flow path of the compressor discharge air to split the flow path into secondary flow paths defined radially outside of and inside of the splitter portion body. 2. The diffuser according to claim 1, wherein at least one of the ring portion and the splitter portion is formed of plural segments. 3. The diffuser according to claim 1, wherein the ring portion is integrally coupled to the struts. 4. The diffuser according to claim 1, wherein the splitter portion is coupled to the ring portion. 5. The diffuser according to claim 1, wherein the splitter portion is mechanically connected to the ring portion. 6. The diffuser according to claim 1, wherein the splitter portion comprises upper and lower portions. 7. The diffuser according to claim 6, further comprising mechanical connectors to conjoin the upper and lower portions. 8. The diffuser according to claim 1, further comprising a supporting assembly on which a combustor assembly is supportable. 9. The diffuser according to claim 8, wherein the supporting assembly is disposed on at least one of the ring portion and the splitter portion within an intra-strut region. 10. The diffuser according to claim 8, wherein the supporting assembly comprises a pad coupled to the at least one of the ring portion and the splitter portion. 11. The diffuser according to claim 1, wherein the lead edge comprises substantially smooth faces tapered toward one another in a radial direction. 12. A diffuser for a turbine engine, including an annular casing to seal compressor discharge air and struts attached to the casing to delimit an annular array of intra-strut regions, the diffuser comprising: a ring shaped annular body having an aft face at an aft facing side thereof, which is supportable by an integral connection between one or more of the struts and the aft face, the ring shaped annular body including:a lead edge, on a forward facing side thereof, which is opposed to the aft facing side and is extendable into a flow path of the compressor discharge air to split the flow path into secondary flow paths defined radially outside of and inside of the ring shaped annular body and the lead edge. 13. The diffuser according to claim 12, further comprising a supporting assembly, disposed on the ring shaped annular body within an intra-strut region, and on which a combustor assembly is supportable. 14. The diffuser according to claim 13, wherein the supporting assembly comprises a pad coupled to the ring shaped annular body. 15. A turbine engine comprising the diffuser of claim 13, a compressor to discharge the compressor discharge air and the combustor assembly, which is receptive of the compressor discharge air from the secondary flow paths, and which is supported on the supporting assembly. 16. The turbine engine according to claim 15, wherein the diffuser is plural in number. 17. A turbine engine comprising the diffuser of claim 12, a compressor to discharge the compressor discharge air and a combustor assembly, which is receptive of the compressor discharge air from the secondary flow paths. 18. The turbine engine according to claim 17, wherein the diffuser is plural in number, with the plural diffusers disposed in parallel with one another. 19. A diffuser for a turbine engine, including an annular casing to seal compressor discharge air and struts attached to the casing to delimit an annular array of intra-strut regions, the diffuser comprising: a ring shaped annular body having an aft face at an aft facing side thereof, supportable an integral connection between one or more of the struts and the aft face, and including a lead edge, on a forward facing side thereof, which is opposed to the aft facing side and is extendable into a flow path of the compressor discharge air to split the flow path into secondary flow paths defined radially outside of and inside of the ring shaped annular body and the lead edge; anda supporting assembly, disposed on the ring shaped annular body within an intra-strut region, and on which a combustor assembly is supportable. 20. The diffuser according to claim 19, wherein the supporting assembly comprises a pad coupled to the at least one of the ring portion and the splitter portion.
