gorgepir,
You are ignoring latest financial results.
I believe you were talking about the xbox not the xbox 360. Since the xbox is no longer produced MS is not losing anything on the original xbox. The 360 as well is now profitable. As for Sony even with the PS2 still doing well Sony announced huge losses. This was all before the last price cut.
So you have Sony announcing a price cut on a product already losing money on each unit sold. Couple that they did it the quarter of the year with the most unit sales and you have the setting for a very interesting financial report by Sony in January. While 360 is profitable on each unit sold and the software sales are fantastic.
Sony will keep the PS3 price currently for at least the first 3 quarters of 2008 as long as the PS3 is selling >175K per month in the US. Microsoft I believe will be looking for closer to 300K per month and a nice bump when GTA IV releases so they will drop price right before GTA IV releases.
Libraries sell systems not individual games
