You'll be lucky to get them by March. I was holding off for the nVIDIA 40nm lower end parts for a folding machine, with, I was hoping, more or the same SPs than a 9800GT/X for the £50 mark. 40nm parts were supposed to have come out this March and the problems with the process have meant delays of two months. The yields are pretty abysmal too IIRC.
Let's see, there's no hope of that, and they're not even here yet, or likely to be here before sometime next month, and they won't be the GPUs that I'm looking for. What hope then the, likely monstrous, GT300?
