Panasonicが発表したLumix GF1の後継機、Lumix DMC-GF2は、Micro Four Thirdsカメララインナップにおける12MPシューターです。
GF2はデザインがいくつか変更され、現在はサイズが小さく軽量になり、LCDがタッチ感知式になりました。

The unit is paired with two optional lenses -- DMC-GF2C (14mm f/2.5 Lens Kit) or a DMC-GF2K (14-42mm Zoom Lens Kit). No price indicated yet but should be announced once it starts shipping in January 2011.
i agree with sylv3rblade. the touch screen will probably make this a bit more expensive than the GF1 and the price point will be similar to entry level slrs.
the olympus e-pl1 is the cheaper choice.
