There is no need to wait until the CPU is available on the market. You can alreadyrun and test programs with AVX using the beta kit of theIntel Software Development Emulator. Admittingly, you won't get a performance improvement for now, but your software will be ready when the processor is released.

Thomas and company,
Ok, I have binaries compiled with Intel 11.1 and see AVX code in the objdump. However I'm getting the following message while trying to run them in SDE v 1.7:
Fatal Error: This program was not built to run on the processor in your system.
The allowed processors are: Intel processors with Intel AVX instructions support.
I'm running SDE on a "non-Intel" processor at the moment.. but plan to try it on a Nehalem tomorrow. Is this the issue? I directed SDE to emulate a processor that supports AVX.. are there other checks in Intel 11.1 binaries aside from this.
I know there won't be any AVX compatible processors for a while.. so it must be intended to be possible to run Intel 11.1 binaries in SDE with AVX enabled, right?
Thanks for any helpful advice. Best regards..

Situation is a little clearer. Seems running SDE on a non-Intel processor doesn't allow you to run Intel 11.1 binaries, at least not those I compiled. Even though SDE provides options for forcing certain features like AVX, SSE42, etc to be emulated.. it doesn't emulate Intel cpus.
To address this.. run Intel 11.1 binaries on an Intel-processor equipped machine. Then use SDE to emulate binaries using AVX from Intel 11.1.
