Finally, some sanity!
This is excellent news. The G series has always been considered "professionals' companions", and this will endear them no end as their most obvious competition in Panasonic dither around with rumours rather than products. Hopefully it will mark the start of a real change, though I'm not too optimistic. Olympus recognise that even at DSLR sensor sizes there is no benefit in going above 12Mp, and are instead focusing (sic) on making the most of that resolution. 10Mp on a 1/1.7" sensor is still a little dense for my liking (23Mp/cm²), but probably unavoidable on a compact, and definitely a step in the right direction... which doesn't have a hope in hell of filtering down to any more consumer-oriented cameras, alas.
