It's been hinted by those in-the-know before....
There was a 3rd well-advanced in the prototyping stage, to be based around the U8500 or OMAP4, more likely the former.*
Now imagine this 3rd device against the backdrop of a team that hadn't shrunk 100% over the course of about 12mth.
I wouldn't be surprised if it had a form-factor similar to that of the 900, & a OS w/built-in utility far greater than WP7x & even Maemo6x (def. less buggy).
And there's no question it would've been on shelves in at least a few countries for at least a month or so by now...
And this would've been in an environment where every review didn't end w/a disclaimer: "Oh she's a nice device but she's dead Jim".

*there was to be 1-2 more after the N950/N9, before Vanilla MeeGo devices were to start flowing from Q3 12` onwards.
(orig. launch was Q4 11`, but the plan was also to focus on 1-2 more Maemo6x devices, in case Medfield/MeeGo needed more time, & they may have)
