Or at least that is the semi-finalized launch date. This means the card will not be released during the CES time-frame. January 22nd 2015 seems to be the date and that fits the reports we have mentioned earlier on.
Multiple shipping manifests already have seen the GM206 based GPU being shipped around. Recently a leaked shipment manifest already indicated 2 and 4 GB GDDR5 6GHz memory versions. However it seems that the GPU is too strong and the biggest change now would be a 128-bit wide memory bus. The card will offer significant powr saving over it's predeccesor and will get just one 6-pin PCIE PEG power header. Pricing is expected to sit somewhere at 199 to 249 USD.
