You may have seen a post or three (or eleventy) over the past few days about Sony's newer, skinnier, cheaper PS3 Slim. Microsoft apparently did, and that might be partly why it chose to delay its own re-pricing announcement, a move it was apparently set to reveal yesterday at GamesCom -- but opted not to. Big Redmond is said to be killing off the Xbox 360 Pro and replacing it with the Elite at the $299 price point, a move it will want to make quickly because, for the first time, it's now the most expensive gaming console on store
