Canon's 1Ds Mark IV Rumor And Two New Lenses?

With current Mark III barely 18 months in production, it's too early to predict for a replacement? You've seen the new 50D Canon launched 6 months earlier, broke its usual 18 months product cycle for the prosumer model, why not the 1 series? In additional to company's Mark III AF hoopla, rivalry like Nikon with recent huge successes on D3 is breathing down Canon's neck. The pro-sport venues has seen the return of black lenses in decade at large margin. I wouldn't be surprised to see the next Canon Mark IV come out earlier than predicted, and likely to pack with jaw-dropping features to regain the market share. Let's see what the Chinese has to say about the next 1Ds Mark IV.
