The future of DSLR, even professional DSLR, is unclear...???

After recent announcements from FUJI and other companies as well, I see a tendency of some camera makers investing a lot of recources in creating a small professional camera, and there is a an obvious market demand for this. I have a feeling that these big cameras ala D700, D3s, 7D, 5D mark II etc. in three years, maybe later, are going to disappear from the market, and photographers will shoot weddings, serious photojournalism... with cameras ala recent Fuji X100... Of course, Nikon, Canon for obvious reasons don't want that to happen, but even they are big players they will be hard pressed by Fuji, Olympus Panasonic, Samsung, Sony to change the concept of digital pro camera... when exactly this is going to happen? I don't know... maybe not any time soon or at all??? What do you guys think about the future of DSLR cameras???...
