I've been saying the same thing as well. I think they'll get acquired before they go bankrupt however. Probably by Microsoft or Google (in this order).
EDIT: I wasn't clear. I meant there won't be a Blackberry device in 2013, but I don't think they'll go out of business.
I used to think a Microsoft acquisition of RIM was near inevitable, but now with the seeming non-suckiness of WP7 and the partnership with Nokia, it seems like MS is doing relatively well on their own - or at least better than they ever have been - with mobile devices.
On the other hand if the current legal climate persists, someone could buy RIM for its patents, and in that case Google or Apple - or an Android user - seems more likely since MS has already been able to use its existing portfolio against Android users.
