Gernot has still been active in these forums, but I'm not sure of his intentions with GLBasic. Development seems to have slowed down as of lately. It's a big job maintaining a language that has grown this large by himself, while adding new platforms, and keeping the platforms up-to-date. He has had a lot of help from members of this community, but even so, it's probably getting hard to maintain. And it's not like he's making money doing this, maybe enough to cover the server costs (I have no idea really).
Physics Engine: There is no built in physics engine. People have ported Box2D to GLBasic, but I haven't tried it, or know its current status. And for 3D, some people were dabbling with iXors(sp?), but I don't think that made it too far.
Particle System: There is no built in particle system. Some people have implemented their own 3D systems in these forums. They look quite capable in my opinion. Do a search and you should find something. Not sure about 2D.
