Sony shouldn't put the EE+GS in because it's expensive.
And who really cares about backwards compatibility. BC has always been one of the biggest farces in my opinion. I just dont think most people, or at least me, care. If you've got the old game, then you also have the old system. Novel concept, that.
And this applying a new coat of paint (720P upscaling, etc) doesn't help those now-ugly old games in my opinion. It just makes them blurry from what Xbox BC screens I've seen. I thin some people even prefer the look of the originals.
I've come around a little bit to where I now agree BC is a nice thing to have..but still hardly necessary.
Do like Microsoft and put it in slowly.
Although, I wonder how the cost of paying an ongoing BC team compares to the cost of putting the old hardware in? It might be less but not insignificant, if I had to guess.
If it's..30 guys (no idea) at 100K each..that's what, 3 mil per year. Still small, probably a very small price, even X360 will easily sell more than 3mil consoles per year, making it <$1 per console to pay the BC team.
