There's no comparable example from MS/Nintendo, original Xbox being irrelevant, as its legs were cut right under it due to production issues where it was shortly discontinued. It was launched 2.5 years AFTER PS2, after it has gained momentum, support, virtually everything. The example is far fetched, if anything this gen launch is the "fairest" launch that both consoles have, on the third attempt.
My point being, MS dropped the ball with 360 support in the last few years of the cycle, which allowed PS3 to pick up the pace, same can happen this gen, and it seems like Sony are already beginning to drop ball with having a famine year right at its launch. I mean I still got PS4, but I virtually got no games that interest me on it atm outside Watchdogs, having to wait for TLOU, so am not really surprised that all PS4 owners would much rather just spam up the forums.
