I just realized your entire post had nothing to do with the next generation, and that's all I wrote about. So here is something a little more on topic :)
No one needs to worry about things that are the same. What sells a product is the things that distinguish it. The 360 has Media Center, better online, better price, It's exclusive games, and the PS3 has Blu-Ray, reliability, more standard features (HD, wireless, bluetooth, etc) and its exclusive games.
When you go buy a car, you don't ask if it has doors. All cars have doors, so you don't care about that when you comparison shop. You just think about the things that set this car apart from the next one. The PS3 and 360 have plenty of those things.
They always will.
