I don't think Intel has an exact date for it yet

If they had a date, I might not ask: There's a reason for that, and I have an example for you! Intel was showing its Z68 platform at CES, complete with Lucid's software solution to enable both on-die and discrete GPUs. I didn't ask further, and was able to discuss everything I'd seen with readers.
I probably would have been forced to sign an NDA to get more details. I said probably because I didn't actually ask for NDA information. You see, had I signed the NDA, I would not have been able to discuss ANYTHING about what I'd seen with the readers.
