Since the Nokia X has leaked so much and so often, I think Nokia is throwing subtlety out the window before it makes a big announcement. On Nokia's conversations page telling users how they can watch their MWC announcements, they posted the image above. See how the negative space between the arrows looks like an X? It could just be a coincidence, of course, but it's a pretty safe bet that this is alluding to the Nokia X.
This device has been one of the most hyped devices we've ever seen, especially considering it's just a budget phone. That fun's about to come to an end, though, as Nokia will very likely make it official within the next week. Hopefully they'll have a few other Android devices in the pipeline for us after the X.
