4 of 5 here. I passed on Omega. Way too big for the character. I'm definitely interested to see what the next one will be. Ideally, I'd love to see a Primus to match Unicron and cap off AotP. My second pick would be a full-sized Monstructor, but I don't see that happening so soon after the upcoming AotP version.
There really aren't all that many releases I can think of at this point that wouldn't be completely viable, or even preferable, as a regular retail release. Aside from Primus, I guess I'd enjoy seeing a Victory Saber-level PMOP/God Ginrai. A full Big Powered set could be good. Or a Grandus & Sky Garry pack. Aside from Monstructor/Dinoking, Predaking, Piranacon, and Rail Racer are combiners that could benefit from the HasLab treatment.
Aside from those, I guess various Commander-or-larger bots could be candidates just for the sake of not using up one of a very limited number of retail slots. It just feels like a bit of a waste to use a HasLab for something like Overlord or Gigatron who could work really well as a retail Commander.
