i don't know about the rest of europe.But it has been available in the netherlands for quiet some time
On the other hand, the E-PL6 has never been officially available in the UK, so this is one place it will be new(ish). Interesting that it will be coming with the 14-42 EZ zoom, hitherto only supplied with the E-M10 on these shores (or separately, for a rather high price).
Interesting hands-on report, nice camera. One observation, though: the customisable mode dial (applying MySets to it) isn't actually new for this model as stated in the article - this very useful feature is already available on the E-PL5 and has been since its launch - that model was the first (and hitherto only) Pen to offer it. Nice to see this feature spreading to new models though.
I agree with MarkInSF - was about to post the same point myself. The G3 definitely has an aluminium front panel, just like the G5 has - far colder than the plastic rear half and top trim. My G3 is early production - unless they altered the build in later ones (unlikely, but not impossible I suppose).
"Interesting" is a good choice of words for the design...
