People will choose their own perception of reality, even if it has little to no bearing on reality. Some will go through greater lengths than others to maintain their delusions.
I'm sure there are those who love their XB360s and liked to say the PS3 was "LAST PLACE" (not third) this generation are probably the same to say that it no longer matters that the tables have turned because the 7th generation is no longer relevant, or maybe that it conveniently ended right before the PS3 outsold the XB360.
Maybe that was the point at which the 7th gen ended to them: right before then.
But I wouldn't go so far as to say users abandoned the XB360 in favor of the PS3. I'd say it's probably the same percentage of owners who stopped using them as those who have stopped using their PS3s.
The Wii, on the other hand, our "winner" for the 7th generation, had users abandoning the platform in droves as of 2010 and most likely stands as the winner in most abandoned/unused console competition of the 7th gen currently.
i was taking note of sony who even after releasing the ps3 continued supporting the ps2 where as microsoft dropped all support for the original xbox which no doubt influenced both japan and europe to be cautious about microsofts insentives with the 360 once the xbox one is launched.
factually speaking the Wii won the 7th gen even after "you say" users abandoned it from 2010 onwards, the ps3 has continued to gain more users though its quality content while microsoft looks like their focus is mainly on xbox one, it would be very naive of any of the big three to stop development for their existing consoles especially with such large user bases.
