The main argument for putting it in the lens is that you can sell a cheaper body and then a more expensive lens. And you purposely limit the usefulness of old lenses. I can put a 30 year old Pentax K mount lens on my K20d body and have image stabilization. Your old Nikon glass on a D40 body won't. Of course at least Nikon made the old glass mostly compatible as opposed to Canon changing the mount.
As for 5-10-20 years, who knows what we'll be shooting. I think it is somewhat difficult for a newbie to make those sorts of predictions and buy according to "needs" because those will likely change. Most dSLRs sit on the shelf once purchased. Others get used like point and shoots (and in fact the owners would likely be better off with a point and shoot). Some get used regularly, and others lead someone into photography as a hobby. None of those scenarios require someone to think 5 years down the road. Only when someone starts buying lenses do they need to stop and think about the system aspect of things.
