We do know their developer prototype though, but that doesn't say anything about commercially available. However, given that they put fairly big (equally sized as Windows@Phone) Bada aside for Tizen, I think they would feel a need to have a few devices out this year... /speculation

Either way, with Jolla and Tizen, there's at least some work for "disruption". When Nokia started taking out their frustration on the N9 before it was even in sales, I didn't see any hope for an open platform.

Edit: clarification: I didn't see any prospects for one.
