why would you wait 6 months when you can use it now? It's already pretty cheap for the performance you get from it.
No point waiting - Ivy Bridge will only be 10% faster clock for clock.
The only point in waiting is if you think there will be a firesale on Sandy Bridge mobos and cpu's.
Don't think Ivy Bridge will be cheap either when it arrives.
So pick up a 2500k and a Z68 mobo that will be compatible via a bios upgrade to Ivy Bridge. P67 will not be compatible.

gammaray: are you building a new system and keeping your present one or are you going to sell off your present parts and upgrade to an i5-2500k?
Here's why. Please don't take this as bragging but I am fortunate enough to have three systems at home (I don't golf rather I build and play with computers). Two of them have OCd 2500k chips and one has an OCd 1100T chip (see my sig below). The Intel CPUs are on the Z68 chipsets and the AMD 1100T is on the new 990FX chipset. The Intels OC better and are faster. However, if you already have a 1090T you have a very fast CPU for the forseeable future. What video card do you have? The 790FX is still a solid chipset and you might be better upgrading your video card and perhaps overclocking your 1090T if you haven't done so..
On the otherside, you will get a good price selling the 1090T but I doubt you will get much for a 790FX mb. The cost for a 2500k is @$229 and a solid mb will set you back another $160. That's nearly $400!
Having all three systems below, the Intels are faster in benchmarks but if I put the fastest video card in the AMD 1100T rig it would narrow the gap if not beat the Intels.
What's your budget?
if you keep waiting for the next thing, you're never going to upgrade.
While that is true, given his present rig, I'd recommend waiting for Ivy Bridge and the next phase of the AMD 7xxx video cards to be released before upgrading.
Honestly, upgrading from what you have to a 2500k seems like more of a lateral upgrade. It is an upgrade, but not a huge one. I personally went from a Q6600 @ 3.2 GHz with a mechanical hdd to a 2500k @ 4.3 GHz with a Crucial m4 128 GB SSD. Now that's an upgrade!
BTW, are you selling your whole rig, or are you going to reuse some of the parts?
With a single 6950 2GB, I went from a PhII 955BE overclocked to a 2500k overclocked. It's better, but I'm usually GPU limited anyway with what I've got.
Given that the 1090T is a solid piece of work, I'd wait. It will still have significant resale value in 6 months due to being about the best AM3 (not all boards can use BD, and to be honest, the 1090T is better than most BD models in most situations).
As a bonus, you can hold on to the 5850, which still holds up well right now, and see how the dust settles between Nvidia and AMD on the GPU side. Right now the 7970 is awesome but ultra expensive, the GTX580 is overpriced and getting old, 6950/6970 are old and didn't offer much over the 5850/5870, etc. It's just a terrible time to spend a lot of money on a GPU unless you just have cash to burn.
