OPM UK had an interview with Lead Designer Karl Jones talking about the future of Wipeout 2048 and what racers can expect from DLCs and the likes-
In summary, what you see in Wipeout 2048 isn't the end of it, it will grow, expand and develop into a whole different beast and with each growth, you won't always have to pay for it.

Official PlayStation Magazine UK You mentioned in a previous interview that Wipeout’s release was not a one shot approach. Can you explain what that means?

KJ I guess it’s going to be patches and stuff. DLC always comes across as paid for content. We’re not obviously not going to just do paid for stuff, we’re going to do free stuff too. That’s largely going to be things we didn’t get time to do. For example, the AR museum.

And the PS3 version?

There's a PS3 version?

MY guess is these updates are for 2048 only and HD/Fury will only get the odd patch for things that relate to them but as of now, HD/Fury is dead, long live 2048.

Wasn't it supposed to be a PS3/PSV game with crossplay?

It is that's why 2048 owners who already have WHD will get DLC with WHD content for free.
