I would. Plenty of PS3 games I'd like to play on PS4, and I can finally get rid of my fat PS3. PS2 and PSONE don't matter too much because I emulate them in 1080p anyway.

Personally I wouldn't since I already own a PS3 but it wouldn't be a bad idea to have a version of the PS4 which offers BC.

I certainly would.

No. I have all the old consoles, I don't Need BC at all.

I'd be cool, but I'd find it pointless since I already have the past PS consoles and I wouldn't want that option since I'd make them useless. If I didn't have the past PS consoles and the 4 was my first PS then yes I'd want that to get those least gen gems.

I'd love an Xbox One backwards compatible PS4.

I still have my PS3, so I wouldn't really care!

Not for £100 more, I'd expect there to be backwards compat in the first place for the same price but that's never going to happen this gen (except for the Wii U which has that covered)

i would but just if it was there as a option. make it standard is not a must IMO. and to clarify, i would because i like to have the best version, not because its essential. i still play my ps3 and its no problem at all to start it up and enjoy it just because the ps4 is right there beside it.

Hmmm. I rather they just make the old backwards compatible ps3 again and sell it for cheap. I hate the idea of "buying" digital versions of old games from the ps1 and ps2 days.
