Yes I would because I recognise that for Sony to release a reasonably priced console for the masses at launch they had to cut down on certain features and that includes B/C. Now for people like myself who have a large digital library over PSN I think it would be very appealing to be able to either purchase a console that comes with B/C or an addon/peripheral which can provide it once installed.
Hopefully Sony will be smart enough to at least provide the add-on option. Having said that though it isn't a deal breaker as I will be getting a PS4 to p[ay PS4 games primarily. And if I need a PS3 fix well my PS3 is working just fine and if it breaks down it is easy to replace and I'm confident Sony will support it for at least the standard 10 year cycle.
As far as what I am willing to pay for B/C I would be willing to pay up to $150 especially if it's built into a premium sku console.
