"The lens was announced alongside the GF1, and it gives Micro Four Thirds photographers a lens option that doesn't currently exist - the 90-100mm (equivalent) macro with image stabilization. Given Panasonic's track record on supply, expect this to ship sometime between the second and third human landings on Mars ;-)"
i think that's because of the domestic demand for the lenses in Japan is overwhelmingly strong.
I just returned from Tokyo, at Bic Camera, Yodobashi, Softbank and other big electronic stores all stock panasonic G and L series camera and accessories very well (and in all colors). Bic and Yodobashi were taking pre-orders, other smaller camera shops were doing the same. won't be cheap though, think it was in the region of 100k YEN.
Well, the dpreview is out on this lens, and looks like I am going to save some money by staying with my Olympus 50mm f/2 macro .
The 50mm f/2 is great, except that it has slow AF, but I can live with it because of its IQ. I thought the Panasonic Leica 45mm would be the m4/3 lens to replace this 4/3 50mm - slightly lighter, faster AF, and 1:1 macro; but, apparently it cannot match the high 50mm f/2 IQ standard. I use the 50mm mostly for portraits, and it seems this application one of the weaknesses of the 45mm Panasonic Leica, at least from the review (which we can take with a grain of salt).
