I'd be happier about it if something decent was coming out for it that I couldn't get on something more powerful. Still lots of great games but the big titles (what few there are) are far superior on the current generation consoles. The PS3 still has one in the pipes I'm waiting for (Tales of Zestiria) but I can't think of a single 360 only game that's coming out to warrant 360's continued support.
I can see it being a great thing for those who don't want to or cant get a current generation console or just want to wait to see if anything great will come out for them (I'm in this category, unless you count wii-u and I personally don't) but I can't justify buying something for the 360 or ps3 that's available for a superior console at the same price, even though it means I'll have to wait to play the game until I have one of the newer consoles.
side note, Its awesome to see new posts from old members! Things have just about come to a stand still here
