To the best of knowledge there were 4 sets... until I looked it up just now! I'm going to assume that the ogre set you're referring to came out as the time as the "starter pack 2", the set with an orc, two archers, and a dwarf dipped in tapioca. I had only just seen starter pack 2 at my local walmart the other day when I promptly picked it up (there were 2 still sitting there, along with a couple of the red dragon boxes).
Since it looks to be a walmart exclusive, I'm going to guess that there are only 5 sets for now. There may come a day that there is a large set 2. For $15, one can only hope.
