This is the first time we’ve heard of September 3rd as an official announcement date for the A900; however, a DPR forum poster says he’s got third hand or so info on the A900 being available in China on September 3rd.
according to retailers of Sony DSLRs in Suzhou China (which is the city next to Shanghai), the Sony Gallery shop in Shanghai should be stocking the A900 from the 3rd.
I’ll note though that the most reliable-sounding info we’ve heard for the A900 unveiling was September 9-10.
Either way, it won’t be long and we’ll stay on top of the latest developments. Expect to see lots more A900 coverage as we approach Photokina 2008.
