This not entirely unexpected turn of events has the side effect of making older GH1 & GF1 cams (ones manufactured at least several weeks ago or earlier) more valuable because they _can_ be updated by PTool3.
There's a possibility Vitaliy may be able to program around Panasonic's roadblock. DVXuser members and others are attempting to apply pressure on Panasonic to relent and release GH1 & GF1 cams without the block, but how successful those efforts will be is unknown.
In any event, it's widely expected that a _new_ camera model—the so-called "GH2"—will soon be announced by Panasonic no later than the Photokina Expo in Sept.
It's been known for awhile the PTool3 software in its current form won't work with a future "GH2", at least not at first, so the road ahead is uncertain but promising.
