I have used exclusively M4/3 cameras so far - I am starting out doing some paid work and I feel the need for an SLR, partly just so I look the part when I do a couple of commissions I've got coming up. 
I like to shoot a lot of landscapes/architecture, and I find the idea of full frame tempting. I also do quite a bit of music/gig photography in small venues - is the AF/ISO on a 5D not gonna cut it in poor light? Bear in mind that so far I have been managing with the contrast detect AF on M4/3 cameras (or manual focus lenses).
I gather there might be updates to the 5D II and D700 relatively soon, so I don't really feel like getting either of them right now, and I'd rather spend money on decent glass at the moment.
Any thoughts? Would be great if someone had used both M4/3 cameras and a 5D.
