E-P1 or wait for GF-1

Well...I like the idea of the Micro Four Thirds System and I was short before getting the E-P1 when Panasonic announced the GF-1.

What I like from the GF-1 is the electronic viewfinder...also the buidin flash is not so bad.

What do you think...is it worth to wait for the GF-1? Anyone know the exact release date?

Thanks...Carsten
