Surprised this hasn't come up much yet... I'm ready to upgrade my camera body and I'm looking for faster focussing system and better high ISO performance and I think we now have some good options. I know that m4/3's is not best suited for indoor sports but I'm not interested in a large dSLR (I'm hoping we'll get some fast m4/3 zooms soon and I'm taking pics of kids not pros). GX1 looks good but I don't shoot raw, and I'm not really interested in post processing. Also, I prefer IBIS. I understand that E-P3 high ISO is not as good as GX1 (older sensor), will that be a problem for indoor sports or will the difference be insignificant? I'm leaning towards E-P3 for the jpegs, but I can deal with post processing if I will get better shots from the GX1. For my other usual uses, I don't think there will be much difference between the two.
