I don't always prefer an aged beer to a relatively young beer (1-2 years), but in this case I think you really ought to hold off. I've had RIS's and barlewines that were actually very tasty after only 1 year and the ROI on waiting didn't seem that great. But this one just calls out for cellaring.
You should try to get some bottles each year for the next couple of years and then have a vertical tasting one night with friends. That way you can directly compare how the younger bottles taste compared to the older bottles.
