I expected Sony to be heavily favored in the polls, just going off of this site alone. Disregarding sales and profits, I have to go with Sony for their variety.
All three have strengths and weaknesses. Sony has struggled with advertising for PS3 games, but again has that variety. Microsoft, while doesn't have much in variety, has proven that their exclusives sell. Halo 4's sales have proven that people do still care about Halo. And going into the next gen at this moment in time, Xbox has a great variety and is bringing it with their exclusives. Let's hope they support One throughout it's life and not for the first few years.
People buy Nintendo's consoles solely for their exclusives. Yes, they could use a new IP. Nintendo games are special (to me), I know I can't play Pikmin 3 anywhere else. Another aspect to consider is that Nintendo games generally do not depreciate over time, unlike a lot of over saturated FPSs. The experiences are unique to Nintendo.
