I kind of agree that most of the big players saw this coming and most are in position to compete... except nikon.
There's going to be more consolidation happening and those companies struggling now... a.k.a. fuji, pentax, richo... will face twice the hurdle soon due to economy of scale. Sony and Canon already cross all 3 boundaries of P&S, slr, video. Nikon and Olympus are left out and if olympus isn't careful, m43 will out live the company itself.
Actually I should also add, there's pain coming from the other side too - mobile phones. Sony's currently the only one who spans all 4 markets, phone -> p&s -> slr -> video cameras. Panasonic and Samsung do too (just not as prevalent on this side of the globe yet). I think with in 10 years... the market will consolidate much like most other maturing markets have and we'll have just a hand full of 5 or so companies left. Any company who thinks they can survive with a niche market *cough* red *cough*... should take note of what's happened in all other maturing / matured industries like the car industry.
Okay now I'm done my blabbering.
