This week will be remembered as a volatile one if you're a MeeGo fan. Just hours after Nokia posted the PR 1.3 update for N9 owners, the company's MeeGo development lead Sotiris Makyrgiannis and other team members have confirmed that they're leaving for greener pastures. The split appears to be an amicable one, with the crew largely going to CloudBerryTec to write mobile apps (including for MeeGo) and consult on software even as they share fond memories. What's left is a lot of doubt over the fate of the swipe-driven OS itself. Nokia promised years of support for the OS as a side project following the big leap to Windows Phone, but it also hadn't mentioned the possibility of important staff departures, either. We've reached out to the company for a fuller answer -- if it turns out that MeeGo development is winding down, the staff shift could be the end to completely in-house OS creation at a company that was once defined by its custom platforms.
