As much as i like EM-5, from a street photographer's perspective, there're couple of problems which a SLT like upcoming A57 addresses in a better way:
1) Aspect ratio: native 4:3, when you crop this to 3:2, you sacrifice resolution....i think it can go to 12MP then.
2) AF: all said and done, the AF still can't match a phase detection body, for quickly shooting moving objects (well, subjects <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='
' />).
3) DR is not an issue with me at all, but current Sony sensors are just plain better.
On autofocus: For street, it helps to have a tilt screen and live view and speed. Unfortunately all faster cameras have dismal live view performance, which means they will not focus fast on live view. EM-5 will be better in this regard, but nothing like a SLT, which has phase-detection capable live view.
On sensor: However improved the EM-5 sensor can be, it can't be better than A-57/K-5 sensor. In terms of size, in terms of DR, in terms of 3:2 resolution, in terms of high ISO noise.
Weather sealing is a great plus with EM-5. Both systems have IS. Both systems have viewfinders and tilting screens.

1-Agreed. But mostly got used to it and grew to like it sometimes. Still there are these times I regret 3:2.
2-I have little experience with street photography but are the subjects so quick they require tracking situations? If not, for Single AF, I think 0.2s (on select lenses) really reached the same ballpark.
3-I agree. Not really "struggling" but they were some occasions I felt a little tight. Will see with the E-M5.
I think you have overlooked something though. Touch focus&capture. I think it's more than a gimmick. I think it's actually very cool. Tilt screen and fast AF is cool, but I think the touch focus is the cherry on the cake especially in those situations you can't really start moving the af zone click by click (although one could argue that you zone focus in street photography?? again, little to no experience for me). I don't think any current SLT have touch screens? Sure they'll come soon enough but I guess their slightly larger bulk would render its single hand holdability slightly worse.
Just my two cents,
S.
