I spoke to a regional executive head of Apple here today and he told me that they have been given indications that the new release of the MBP will happen only with the new OS X Lion. This clearly means that we can expect an upgrade only in April 2011, as that is the time around when Lion will release. He clearly told me that is 'highly unlikely' that Apple will be releasing the updated version of the MBP line just a few months before the Lion and the updated version will include the new OS X Lion. Personally, I think this makes even more sense w.r.t Sandy Bridge as this will also give Apple more time to test the SB performance and develop a solution towards the space constraint vs Graphic card vs Optical Drive problem in the 13" MBP(Its their bestseller after all!). Cheerz!
