UFC - Georges St-Pierre v Anderson Silva at middleweight this year?

The UFC could put together a huge middleweight fight between Georges St-Pierre and Anderson Silva later this year Speaking prior to Saturday night's UFC Fight for the Troops 2 show, UFC president Dana White said on a video blog that should current middleweight champion Silva defeat Vitor Belfort next month and GSP then beat Jake Shields at UFC 129 in Toronto in late April, then St-Pierre will make the move up to middleweight.
That would mean GSP v Silva taking place in the second half of 2011 in what would almost certainly result in one of the UFC's biggest pay-per-view buyrates in history.
GSP has previously stated that should he make the move up to middleweight then he would stay at that weight rather than than cutting down to welterweight again.
Silva v Belfort headlines UFC 126 on February 5th in Las Vegas.
