360/PS3 the longest and biggest gen ever. Many gamers with large entrenched libraries. No back compat on new consoles. PC library goes 20+ years back. You've got to be crazy to jump into next gen or to perpetuate the idea of a console generation at all.
Game purchase granularity--how much? I’d rather AC, BF and others de-couple SP and MP modes so I only had to buy the one I want (and only incentivize further development of that type). But, often devs/pubs try to have and eat the cake both (forza 5, ME3, others) buy offering granularity AFTER the full purchase.
