I'll go +1 for Maccruiskeen too and add my not-so-diplomatic contribution:
Do those of you who are consistently negative in your attitudes towards 650B have any idea how big the bike industry is? That the production volumes of suspension forks from the likes of Fox, Rock Shox, DT, Marzocchi etc are staggeringly huge and these manufacturers will be committed to supporting their existing product lines for the same number of years as they currently do and more for service items. You guys really need to get out more and stop developing irrational fears that you are being personally persecuted. Seriously, that path leads to all kinds of delusional self-importance and paranoia. The world is a big place and mountain biking is wayyyyyy bigger than this forum!
As has been mentioned earlier, how many parts could be transferred from a top end 2003 bike to a top end 2013 bike? Possibly stem, bars, grips, pedals and disc brakes and shifters if you wanted to stay with 10year old technology. None of those bits are affected by wheel size.
Recognise your inner child, reassure it that everything is ok and then move on and embrace change, for your own sakes.
