After seeing a post by mikaok on an early Bulldozer review I did a few searches and these CPU's are now expected to be released towards the end of July (bear in mind that they were going to release on 20th June).
Some early reviews suggest the 8 core versions will slightly outperform the i7-2600, but how they will perform here is open to some question. Their architecture is not quite 8 core - not in the way a Phenom II quad has 4 full cores. The top Bulldozer CPU will actually have 4 full cores each of which will have 1 floating point core and two Integer cores. With only 4 floating point cores relatively performance of these CPU's might be poor for some projects, and the Floating Point records here might remain unchallenged.

So my question is,
Which WCG projects are Integer intensive and which are FP intensive?

Exciting news! Do you have links for the above points? I'd love to read more detail.

From wikipedia

http://en.wikipedia.org/wiki/AMD_Bulldozer

Bulldozer will be the first major redesign of AMD’s processor architecture since 2003, when the firm launched its Athlon 64/Opteron (K8) processors, and will feature two 128-bit FMA-capable FPUs which can be combined into one 256-bit FPU

This is where the one FPU shared between 2 CPU's comes in

2 CPU's 2 128 Bit Integer Units and 1 big FPU capable of 2 128 FP calcs per tick = 1 Bulldozer Module

Currently up to 4 modules per AMD3+ socket

This is hardware supported hyperthreading

Might be, but certainly won't be released on 20th June!
Then there was July...
...and now we are talking about 19th Sept.
I suppose it's only 3months, but it's still a disappointment. I guess they learned a lesson of the early phenoms, TLB, and want a successful launch, unlike Intel's i7-2000 series with it's USB-chipset design failure. AMD have a record of releasing CPU's and continuously adding to the list, so I suppose there is no rush.

On a positive AMD note, their GPU range might get another lift later this year with the release of 7000 series Radeon HD GPU's. Trendgadget claim's AMD already has 28nm samples.

28nm is a notable jump from 40nm; the 55nm to 40nm was a reduction of 37.5%, but this will be a reduction in Fabrication thickness of 71%. This will bring improved power efficiencies in lower to mid range cards, and at the top end every Watt of efficiency will be put to improved performance. I expect a performance jump this time. The last 18months brought new technologies, this time it's more about speed. But take the speculation of a Sept-Dec release date with a pinch of salt. Ideally both the CPU and GPU would turn up around the same time, before school starts up (somewhere), before T/G or Christmas.., but history tells us such plans tend to go wayward. I see high end card becoming available early next year, rather than this year. NVidia tend to be a bit behind in their release dates, so I would be fairly sure they will not turn up this year.

looks like I will have even more time to keep saving those pennies
