Sony could just take literally Nintendo, stressing the fact that its own home consoles can work fine with both glasses and glasses-free tech and letting people believe (not lying by any means, but just quoting Nintendo's bashing of glasses tech) that Nintendo home consoles, instead, will have to wait for glasses-free tech. So the only way for Nintendo to avoid a backlash would be to state that glasses tech is perfectly fine waiting for glasses-free to evolve enough for the living room.
