Asian rumors cited by TPU claim NVIDIA's GK104 "Kepler" GPU will continue to have a 256-bit GDDR5 memory bus. The card has a pretty high power consumption of 225W, but according to the rumor this GeForce GTX 560 Ti successor aims to compete with AMD's Radeon HD 7970 series.
New reports suggest that this GPU, which will succeed GF114 (on which the likes of GeForce GTX 560 Ti are based), will continue to have a 256-bit wide GDDR5 memory interface. An equally recent report suggests that NVIDIA could give the front-line product based on GK104 as much as 2 GB of memory. We are also getting to hear from the INPAI report that on this product based on the GK104, the GPU will have a TDP of 225W. What's more, NVIDIA is gunning for the performance crown from AMD Radeon HD 7900 series with this chip, so it suggests that NVIDIA is designing the GK104 to have a massive performance improvement over the GF114 that it's succeeding.

Going to be months, perhaps half a year or more before we see successors to the 580 and 590 series. Doubtful they'll have much to compete with AMD until then.
As soon as AMD's high end starts shipping it's going to be a dry few quarters for Nvidia...
