I say enjoy the x100s now and worst comes to worst, you lose a few hundred on the used market if you end up having to upgrade.
Aftermarket where I live sucks balls. Everyone wants the latest of its class and depreciation cost is quite high.

As to the whole fixed lens worth it? Well in my very personal opinion it does as long as it's the good one for you. I'm just looking for my 5d3+35f1.4 combo IQ in the smallest (and rugged+sneaky) package possible.
