Does anyone remember the old Nokia WP7 Concept(s)?

It's been pretty much a year since Nokia announced their partnership with Microsoft. And it's been quite a year, with the announcements of the Lumia series and the beautiful 800/900. But what happened to those concepts that they presented when they announced their partnership? Those were beautiful renders and quite frankly, they seemed like a very doable design. Sure, they looked a little Samsung Focus-esque, but given that it's Nokia I think they could have easily upped the build quality. Plus, they were original designs. Not a recycled design from a phone that's headed to extinction. And now rumors of a Symbian alternative with the 800 design? Here's to hoping that Nokia keeps the Lumia design at least somewhat exclusive and high-end, and that they present these concept beauties as production models at MWC.
