Interesting! That could get RIM through the rough patch to the 10 release. That London device looks pretty sweet. If they get a decent activestink client on it it could be a decent option, although they will be sooooo behind appwise at that point
By the looks of it, with the timing, the Blackberry 10 phones look like they will be coming out around the same time as the iPhone 5 and possibly even the Windows Phone 8. Not good timing for RIM, again.
The only way RIM will stay active is doing the licensing thing with their technologies. All the mobile OS guys are trying to build their access to patents, through purchasing companies or through licensing, and RIM has been around long enough that they still have a lot of valuable ones. If they can get licensing fees, it will be their saving grace. And it sounds as though that's what Microsoft is interested in.
For the BB10 devices, they need to focus on one or two great phones and build on them. If they continue with having too many handset choices (Torch, Bold, Curve, etc.), they won't do good. If they focus on one or two great phones, and then maybe license the BB10 OS to other handset makers (Samsung sounds interested in that), RIM could possibly have enough luck to pull through the rough patch they are having. But going the licensing route is the only way I see them making it.
As it stands now, even though they are a Canadian company (GO CANADA!!) that I've been supporting over the years, doubt I'll be getting another Blackberry when my contract expires.
