NVIDIA Geforce GTX 275 Official Specs Look Promising
 

The chip works at 633MHz core and 1164MHz memory and just like the GTX 285 it has 240 shader processors.

It still has a 448-bit memory interface and uses GDDR3, and at this point it definitely looks like a GTX 295 chip with a higher clock. It is a dual-slot card with a single GPU and it should be selling for $249 in the US, or €249 in Europe, the card should be out in the second week of April.
