Personally I'd rather see an excellent and affordable 4/300 DO that competes with the Nikon 4/300PF.
600 DO seems too obvious but also more expensive than the 600f4ii? A 300/4 DO, now that would be an interesting lens. My biggest concern is that the DO design doesn't take TCs as well which is a real benefit to the current 300f4. A lot of people seem to want the 400f5.6 refreshed and include IS, this seems pointless with the 100-400ii as good as it is. Id rather see a 300f4 with an across the board improvement. Updated IS, AF and sharper at f4.
Yes, 4/600 DO will probably be similar or even higher price than 4/600 II; there's also the rumored 5.6/600 DO but even that will cost about the same as a small car probably ;-)
Just looking at the 4/400 DO or the Nikon 4/300PF, TC's are not a problem for recent DO lenses except if you are extremely critical. Both do very well with a 1.4x TC, with 2.0x in addition to some optical quality loss the AF becomes a problem for moving subjects and in that case you should probably start with a brighter lens like the 2.8/300 II.
A much improved 4/300 DO could be my dream lens
I'm currently using the 4/300IS but consider switching to 100-400II instead despite the much higher weight, because of the better AF, IS, better reach and better closeup capability. Agree that the 100-400 doesn't leave any room for a 5.6/400 IS (except maybe lower weight, but I think the market would be too small also given the significant used market for the 5.6/400).
