Another option is that I may end up, if a upgraded D300s does not appear, buying some new glass. I already have the 70-200 VRI and 16-35mm + a 300mm f4 amongst many others. Unfortunately, that will leave me with two ever aging cameras.
To add an insult to Nikon I will be so disappointed not to see a D400 etc and if Canon replaced the 7D, I will be tempted to keep Nikon as my landscape and portrait gear and switch to Canon for my wildlife. That is something I really do not want to do, but if needs must then I may well seriously consider that option
It will in fact be interesting to see if Canon release a new APS-C semi pro body. Personally I feel that if Nikon don't, Canon won't as the dSLR market is now moving in other directions.
