To be honest... if you have the space, keep it. If in doubt if you will use it in the future do not buy anything new.
I think that is the best way to do it. There have been many times over the past 15 yars, when I have thought that the group I was playing with was breaking up and that this would be the end to it and I have always come across other people to game with. If I remember my trip to Canada Alberta and Edmonton are not close, but only an hours drive from where you live. So if push really comes to shove, you will only play less often, but I really doubt you will ever completely leave the hobby. I think were all like US Marines... we never cease being Marines... err Wargamers.
And like someone said... I have never heard of anyone who did not mourn selling off a collection!
Cheers,
Burkhard
