Can we all please stop the endless childish whining about backwards compatibility?
Just seems that we had a few consoles that did feature backwards compat. namely the PS2, PS3 (more or less) and the Wii (but only because the Wii is just a GameCube with motion controls in it's core) and now we expect every producer ever to incorporate it in their products. Why? I don't recall a global outrage when the SNES, NES, N64, GameCube, Sega.. etcetera.
Pretty much the decades before the 6/7th gen had limited or no backwards compat on followups with completely different hardware.
