Well, based on current situation, XBO clearly has better chance of reaching second spot.
That said, XBO is losing to its direct competitor right now (PS4) and I really don't see how it may turn things around in this regard. (I may be wrong but the little difference in power is going to matter because third party games are almost always going to be slightly better on PS4)
Because of that the XBO for me is pretty much locked to half the PS4 sales. (which is gonna be ok even if not great)
Nintendo, however, is not part of this direct competition (because completely different games). For that reason, it is easier to imagine something completely turning things around for the WiiU (Amiibo might be a candidate).
