No, the US Consumers would be angry when they learn about it, too many "OLD 360" would be traded in by the masses, and people would be demanding the new one or jump over to PS3 market (Which ever comes first). It would be the biggest headache.
Microsoft turning into another Sega by releasing another edition or modded version of their system or what? It needs to end. Variety is great, but man it's a pain and CONFUSING to sit there and explain 3 to 4 systems of the same brand to a customer over and over again.
Sony is guilty, Microsoft is guilty. Nintendo...simple...1 Wii, 1 DS Lite to rule them all....
Microsoft making a Core Unit, a Pro Unit, and an Elite...then giving users an optional HD-DVD player claimed it was paying the same as a PS3 (which was a lie)...then which bombed...and everyone is dumpin' HD-DVD quicker than Paris Hilton's career.
Sony made a 20GB, 60GB, and an 80GB...1 that plays everything perfectly...1 that does jack squat when it comes to PS2 games with a fatter drive....1 that can't connect to the PSP (20GB)...killed them off...now a 40GB...then another 40GB with no free movie...then a rumor of 120GB or 160GB.
*phew*...let's just say, out of all the systems I've seen in my time, this is the biggest market blunder and there's really nothing we can do about it, since they have the market on the strong hold.
