My vote goes towards the awaited snapshot and update to HTML5. That is, they may have deemed them more trouble to deal with than they're worth.
Would also suspect dev difficulties in working with FKG's code. Could be more intricacies in there that they have time to spend.

Is there any info out there listing the approximate generated revenue for games? Thought FKG fared better than some of the other games here which are pretty spend heavy.
