They should theoretically be able to create much smaller lenses now with the shorter back focus distance and smaller diameter lens mount. So hopefully they'll design some ultra compact zooms to go with it. IMO Olympus already has the most interesting range of SLR zooms from any manufacturer (they have a constant f/2 zoom for god sake), so hopefully they'll focus all their attention on the M43's system now. I don't see how they'll be able to make a zoom small enough to fit in a pocket, so I imagine pancake primes will be needed for that. That's fine by me; you could then mount a new version of that 12-60mm on it and throw it in a back pack when hiking and still have plenty of room for other stuff. As it is now my Flipside 200 pack is totally full, but with this system I could actually put a snack or a bottle of water in the slot currently occupied by my Tamron 70-300mm.
Imaging Resource has the best write up on the M43 I've found so far. Instead of just pasting the press release like everyone else they actually dove into and explained the potential this system has and speculated on where it will go:
