That is correct, Moguri has recently started to work on a staging branch for new BGE development.
Yesterday for example, he cleaned up a lot of unused Blenderplayer code files that as of now was only serving to make things messier.
Today, he’s starting to add new features and optimizations, including…
Debug Properties for Added Objects (from HG1).
And animation culling for objects using armatures (speeding things up by keeping the amount of actions playing at once to a minimum).
It seems like BGE development is still heating up as we go through the Summer, I could imagine the BGE having a strong finish as the 2.6x series wraps up. So if you were impatiently waiting to see some BGE development activity, your wait is over.
