I'm approaching the point where I'll need to decide on either buying another (4th) lamp for my AE2000 or replace it with an AE7000 or, perhaps, AE8000. I'm interested in using 3D as a novelty, but haven't fully bought into the technology. I'm a novice, but understand that the 3D is evolving from IR based to RF based (which sounds like a good thing). Should I wait to see if the AE8000 (maybe this fall but maybe 2013) incorporates RF transmission? It looks like that is a very likely possibility. I would hate to be stuck with old tech IR glasses if "new and improved" is right around the corner. Thanks.
