This means, Olympus are willing to give up the tele advantage.
The tele (and macro) advantage doesn't come from the crop factor, but from the pixel density.
The 15 Mp Canon 50D has about the same pixel pitch as a 10Mp 4/3rds camera, so a 300mm lens on the Canon has the same reach as a 300mm lens on the E-3 (assuming equally sharp lenses, but Canon's tele lenses are highly regarded).
A 12 Mp 4/3rds sensor will have similar pixel pitch to an 18Mp Canon APS-C sensor. If Oly stop at 12, there is a clear risk of losing the tele reach advantage to a future 60D, D400, K30D or A750.
And all this comes from the misconception that smaller pixels give worse image quailty. There is no evidence of this. Worse pixel quality, yes, but not image quality. 12Mp will not extract all that the lenses can offer. It's a bad idea.
