BC is important to many people though, let's not say it's not. Perhaps to the causal gamer it's not as big of a deal, but to those that have an awful amount of titles, not having to switch between consoles is a plus. I'm all for ditching an older console if the latest handles everything before it. Keeps things tidy and much less of an annoyance in general.
Also, having to emulate each game is just a pain in the ass to keep up with it, so I wouldn't expect tons of titles available. Just ask Microsoft, there are still many games I wish they'd get to work on and make BC but it looks like a pipedream at this point.
Although Microsofts BC fiasco was due to them switching to ATI for the GPU, thus causing problems with NVidia. Which is why MS had to resort to software emulation in the first place instead of having a hardware solution.
