We already seem Bloomfield in the single socket Mac Pros.right, so it would run warmer, require additional space inside the iMac, cost more, and use more power. So will we be seeing the bloomfield in the mac pro's?
Gainestown would be the same component only with the second QPI link enabled and the added cost to have it toggled on as well for DP workstation/server solutions.
The license was only for products that used the front side bus.Intel signed an agreement with nVidia 5 years ago to allow nVidia to produce chipsets compatible with their processors. The new nehalem architecture has a different memory controller (or something of that sort) and Intel says the contract is no longer valid, meaning nVidia cannot produce chipsets for the new processors. Nvidia argues the opposite, that the contract is still valid.

I've seen several examples of how nVidia would handle the DMI/QPI interface in addition to handling the IGP but it's of no consequence since they're not going to make product for Nehalem/Westmere.
