I just read the article more thoroughly and the new WA cards will supposedly work in Write Acceleration mode with many of the pro D-SLRs. The Nikon D1X and H and the D100, the Kodak 14n and 760 models, and a few others. The Canon line is not mentioned, but the cards may still work in standard mode even if not in WA. The Fuji S1 & 2 were not mentioned, but if you go to PMA or know someone who is, you could ask about that. The Fujis might work in standard, non-WA mode.
