I don't see why it shouldn't go in the PHB2. The PHB1 is "Arcane, Divine and Martial power sources", so the PHB2 very well could be "Mental" power source.
I think that a single power source PHB would defy the concept of "one PHB each year" I expect the introduction of new power source but also expansions of old power source
what are they going to put in the annuals PHB otherwise?
skill will be in PHB1, lots of feats and talents and combat rules will be in PHB1 and they are not going to reprint each time the same stuff
so each annual PHB will have new power sources, new feats, new talents, new spells, new classes for new and old power sources, mixed-classe that match and mix power sources and so on
my question is how many Power Source can be done

I did a little list on another thread: Nature (could be split in Living Things, Weather), Psi, Chi, Spirits of the dead/ancestors, Spirit of Animals, Negative, Positive, Social, Sexual, Fey, Leyline, Elements, Stars, Music, Poetry.... and you can go on and on
