Wait for E-7 or m43 with new 2.8 lenses

Thanks everyone for their opinions and comments.

I wanted the em5 with the 2.8 lenses for smaller package and to take everywhere where I go. E-5 with 12-60 can be a little bit heavy after a while. I shoot some events and/or weddings... as well some portraits in studio and outside... but I use the E-5 as well for personal pictures... here is where the E-5 is very big and heavy... I got the xz-1, good but still not enough. the E-M5 with those lenses could be use for both situations. but still wondering advantages and disadvantages.

I appreciate all your comments guys. Thanks a lot... I really love my E-5 and my HG lenses with the PL 25mm 1.4. I always wanted something like 35-100 for portraits, but the Olympus one is very out of my budget. For that I use the ZD 50 2.0 and the PL 25 1.4, but I know the 35-100 would do better job.

Maybe I should keep saving for it.
