According to the below site, launch tomorrow October 26 with shipping starting on 11/2. I expect reviews of the GPU to be released any day now. I'm sure hardware tech sites have already done so but are still locked under an NDA.

The question is going to boil down to availability and if those stupid miners start hogging the supplies up. I am so sick of them ruining the GPU market for we gamers.
