Just one thing: Wonderbook is not the same as Book of Spells. One is the hardware, one is the software that comes with it.

Your OP asks "Will Wonderbook keep selling?". Well yes, I think it will. The AR book will most likely be bundled with whichever game next comes out for it (Diggs Nightcrawler or Walking with Dinosaurs) so will sell more whenever they release.

Whether Book of Spells sells any more: probably not. Sony's big advertising push was over the holidays and like other people have said, it'll slow down dramatically in the coming weeks.

Is the Wonderbook sold seperately from the game "Book of Spells" or are they force bundled?

Is this considered its own IP? Like the next book would be called something else?

I'm not sure they are sold separately at this point, actually.  There would be no point, because buying a Wonderbook right now has absolutely no purpose unless you have Book of Spells.

The best way I can think to describe it is: Wonderbook is a peripheral.  It's a piece of hardware similar to the PS Move.  Book of Spells is a piece of software.

Diggs Nightcrawler, when it comes, will be able to be played on Wonderbook if you already own one, or will probably be bundled with one otherwise.  You won't need a brand new piece of Wonderbook hardware to play it.

I hope that makes sense.

People seem to be forgetting about the massive advertising that this has been getting.

wait this thing actually sold i am pretty sure everyone was either asleep or booing it during sony's E3

This was the perfect product to do great on christmas. + you can't have a better name to back it up than J.K Rollings. Neverless, despite these two factors it only manage to do 300k. Sales will go back to close to nothing now that christmas is done.

And my prediction is that Sony, like many other ideas they had that did'nt have a easy success, will give it up and we will never see a other wonderbook game again... (maybe 1 in the case that it had already a other game in developement but that will be it)

well i think it can sell to the younger market with dinosaurs and magic etc but probably really a holiday seller

It's based in the Harry Potter universe and it is sponsored and written by J.K. Rowling which translates to license fees and endorsement fees which are most likely really steep given the success of the franchise

as long as they keep creating good stories for WB, i don't see why not.

Wonder book is going to surprise people. With Diggs night crawler, walking with the dinosaurs and what ever Disney is doing it's going sell very well. Not bad for recycling old tech.
