In the short run, it means that I will focus on strengthen 3.4, fix bugs, bring back some kind of templates, etc etc. In the long run, Cocos2D will continue, but how much V4 will be delayed / what other options we have / earth is invaded by aliens / simply is speculation at this point.
Bottom line is, that Cocos2D has been around for many years. That is not going to change.
Apportable has contributed a lot to the development, but all good things will eventually come to an end. I have always believed in, that when one door shuts, another one opens.
Cocos2D will continue to support SB1.4, so from my pow, everything should continue to work.
