This is why next-gen consoles have to represent a quantum-leap over their predecessors.
Quantum leap would also entail a correlating increase in price...technology doesn't work well with quantum leaps, gradual increases are better. We went to the moon just fifty years after barely flying bi-planes, and look where it got us. That was an abortive attempt at a quantum leap. Consoles and other tech needs to be noticeably improved/better/more powerful than predecessors, which X1/PS4 are. The problem is that 360/PS3 are excellent devices and super successful. X1/PS4 have it hard, just like PS3 had it hard in 2006-2009. PS2 was super successful, while 360 took over from a console that was not, so it was easier to establish.
The curse of the previous generation is why we're going to wait another six months to a year before all of those delayed titles decide to show up, and why prices on 360/PS3 are not dropping so fast. Why should MS and Sony mark them down to $100 when PS Vita TV with a controller can sell for $140?
