Probably not a big enough market for it.
Intel's upcoming quad-cores aren't even based on the Itanium IA-86 architecture. In fact, they're based on the Core Microarchitecture.
Desktops
Conroe - First eighth-generation desktop chip, 65 nm, dual-core, 4 MB L2 cache
Allendale - Dual-core, cut-down Conroe with 2 MB L2
Kentsfield - Quad-core MCM, consists of two Conroes, with 4 × 4 MB L2
Millville - Single-core, cut-down Allendale with 1 MB L2
Ridgefield - Dual-core, 45 nm shrink of Conroe, with 6 MB L2
Wolfdale - dual-core, 45 nm shrink of Allendale, with 3 MB L2
Perryville - single-core, 45 nm mobile and desktop processor, 2 MB L2
Yorkfield - eight-core MCM, 45 nm, 12 MB L2, successor to Kentsfield
Servers and workstations
Woodcrest - First eighth-generation server and workstation chip, 65 nm, dual-core, 4 MB L2 cache
Clovertown - Quad-core MCM, consists of two Woodcrests, with 4 × 4 MB L2
Clovertown-MP - MP-capable version of Clovertown
Tigerton - Quad-core, MP-capable. Originally, instead of Tigerton, a processor codenamed Whitefield was intended to launch. Whitefield would have been a true quad-core (i.e. not an MCM) and would have used the Common System Interface bus. The differences between Whitefield and its replacement, Tigerton, are unknown at the time of this writing.
Harpertown - Either a dual-core, 45 nm shrink of Woodcrest, or an eight-core, 45 nm MCM with 12 MB L2
Dunnington - Four to thirty-two cores, successor to Tigerton
