I think JCL will keep the Gamestudio project running with minimal effort as long as some sales still trickle in (like he already seems to be doing since a while) and at some point in the not so distant future it won't be worth it at all anymore.
seems it may be happening already, i mean, even a bug i mentioned weeks ago still isnt fixed and the forecast page is damn pathetic, theres NOTHING there, as if they think the engine is complete, a game engine is never truly complete, not with new technologies being released, everything from physics to rendering can and should be changed/optimized
