Jolla has been quite non-commital about if they're running on ARM or Intel. My take on the whole thing is that Jolla is or was having talks with Intel (pretty sensible anyway, as Intel was a MeeGo partner). But whether it will be Intel depends on how much Intel is willing to commit to the partnership. The whole situation is of course complicated by Tizen with Samsung. So in the end, it's money and politics. Like always. Anyways, Jolla is our best hope for future and I'm rooting for them whatever the underlying architecture.
