I only buy a new console when there's a game that i really, REALLY want to play. I don't think too much about the overall library, as most other seem to consider carefully when they invest in something.
As an example: I really like Soul Calibur, so i bought a PS3 when SC4 was released in 2008. I also really like 2D Mario games, so i only bought the Wii when SMB. Wii was released in 2009. So the primary reason why i got WiiU as early a i did was because i REALLY wanted SMB.U. I didn't even THINK about what support it would have or not have. I simply dont care. Why? Because i got the game i wanted :)
Does that mean i wouldn't be buying any other games? Absolutely not, but i need a primary motivator when buying a new console. Everything else is secondary.
