there's no VR II lens.. not yet anyway.. there are a lot of rumours that Nikon will make an update for this lens.. they probably will, but when that is, no one can say for now..
so if you need the lens to shoot something soon, just get the one available.. if you are willing to wait an unknown time until Nikon announces the update for this lens, then by all means.. remember also it will take some time at least before being easily available, from the date Nikon announces something new..
just as a sidenote, the current 70-200m lens seems to be a fantastic lens by most accounts.. and when/if Nikon does update it, I'm quite sure it will be better(would otherwise defeat the purpose of updating it?).. The question is, how much better? and will most users need or be able to tell the difference?
