Different ps3 models

[Gamekid]

It has taken quite some time for sony to produce different models of the playstation 3 and while the variety is nice. I don't really see a point in having 4 different models to choose from. From launch time, we had the 60 and the 20 and everyone went for the 60. Then came the 80, which was like the 60 plus 20 extra gigs of hard drive space, a freebie game and less backwards compatiblity with older ps1 and ps2 games. Now we have the 40, with no backwards compatibility for ps2 games and I hear that it could be done with sofware emualation. My question is this, why even do that? It wouldn't make any sense to eliminate ps2 support from a ps3 and then add it in via software emulation. Sony calls the shots on different models, but I really think that we should only have a few models. Take the 80 out and have the 40 only support ps3 games. That would get the cost down more then at $399.99. Now there is a rumor that a 120 GB ps3 is in the works, but why add that to the lineup? It's nice to have variety, but I really think that sony needs to not have so many models to choose from. Going with software emulation is not a good idea because you can't get the list to be 100% complete, at least microsoft can't according to wikipedia.
