I might be getting thew wrong picture, as I don't really read up on all the news, but a couple of items of news I've heard lately have made me think the Digital SLR world might be up for a big shake-up. 1. Konica Minolta leaves camera business and sells mount to Sony. 2. Sony makes the sensors for Nikon DSLRs This reminded me that Sony uses Carl Zeiss lenses in their consumer cameras, which have a reputation for being great lenses, to the point a significant number of pros who aren't happy with Canon's wide angle lenses, use manual focus Zeiss lenses with an adapter on Canon bodies. So not only could Sony make an SLR and have great lenses supplied, but they could undercut Nikon's prices as far as sensors go, or sell Nikon less attractive sensors, as in older generation or whatever. Nikon would be in a bad position if they depend on a competitor for their supplies in any case. For people who don't believe the Nikon/Canon dominance can be upset, there is a clear parallel. The Nintendo/Sega situation in the 90s, and look at Sega now after the Sony's Playstations.
