Yeah, out of what I could see co ing out for now, the pictured Bard is one I'm holding out for, and I could see a Bolg coming out around summer time, like Azog. Especially since there's now a gap in the range - there's a Bolg profile but no 'Bolg' to be found on the store.
I wouldn't count on much else, but you never know. If they're unwilling to sprinkle hobbit stuff as and when, and want to wait for a otherwise quiet week to release a bunch of stuff, then we could see some surprises. I don't think anyone expected another Thranduil or Beorn the Man, but sure enough they showed up. I'd certainly not say no to Legolas and Tauriel in their travelling gear, or some Dwarves in their laketown getup.
Expect a further three gandalfs.
