Do those sources also imply that Canon will have something equivalent to the Nikkor 18-200mm VR in the foreseeable future?
No, of course not and I am certainly not suggesting that the Nikkor 18-200mm isn't a very fine super-zoom. I suppose the question that only BertNoir can answer is whether, given that he is interested in a semi-pro body, a superzoom is what he wants.
By way of illustration, in the UK a D200 body plus an AF-S DX VR 18-200mm 3.5-5.6G IF-ED would cost around £1260. The Canon EOS 30D Body is currently £560 so, speculating wildly about a camera that doesn't officially even exist, let's say the 40D will retail at £650. That leaves around £600 in the budget which will comfortably buy an EF 24-105mm f4L IS USM lens. Looking at the
SLRGear.com Blur Index results suggests that optically that Canon lens is the sharper choice. Given the difference in price and more modest zoom range that is hardly surprising and I definitely don't want to cast aspersions on the Nikkor.
BertNoir,
Hope this friendly banter isn't a distraction. It is both a benefit and a drawback of forums like this that you can end up getting more advice than is helpful. If your heart is with the D200 then please ignore all of the above as both it and the Nikkor lenses are fine choices.
Bob.
