The interchangeable-lens compact war is raging harder than ever. This morning, Olympus updated their PEN line with three new options, including a new flagship in the E-P3. The new line-up is rounded out by the E-PL3 and the smaller E-PM1. All three have a 12.3 megapixel Live MOS sensor, TruePic VI image processing, in-body image stabilization, 1080i video and a revamped interface. Olympus has also bumped the maximum ISO to 12,800 across the board and added a grip of Art Filters and "creative features" which may or may not appeal to you depending on your style.
