So I've just recently dropped Warhammer 40K and I've been eyeing switching to Infinity. Seems like a much better game overall. But I have a couple of questions.

With 3rd Edition waiting to drop from what I've been hearing, and base size changes to units about to be enforced, is now a good time to get started buying models or should I just wait until the new stuff is released? 40K 7th Edition just burned me in a similar manner, and I don't want that same thing to happen here.

I ask because Infinity models don't seem to be easy to find where I am, so I kind of want to snap them up while I can.
