Not really. Nintendo might have to do the same with the Switch 2. If they had just stuck with their aging console, they might have managed costs enough to keep the price the same or even cheaper.
Well, truthfully, consoles today are just PC components. So I guess backwards compatibility is mostly a non issue. It's not like the old days where they would have custom ASICs.
Check out Star Trek Continues on YouTube. Excellent "fan" made series. I quote fan because it's obviously on a level beyond typical fan created stuff. Looks identical to the original series - lighting, sound, etc.
Does anyone really care about backwards compatibility? For me, once I move to the next gen I don't go back and play older system games. Other than for nostalgia's sake.
