GeForce GTX 280+ (GT200-b) in September? GTX 350 (GT300) in Q4/08?

According to AustinComputers in Austrailia, it looks like Nvidia is rolling out its 55nm GTX 280 (supposedly called GTX 280+) this month. Additionally, a GTX 350 is expected within the close of the year, featuring 2GB of GDDR5 on the same 512-bit bus. If this product page is correct, this new card could easily be a beast!
