Leaving Switzerland 2nd pillar question

We're leaving Switzerland in the fall. I've recently stopped working. My husband will work for a few more months.

I'm a US Citizen so I know I have to cash out my 2nd and 3rd pillars, and need to close my accounts within 2 months of officially leaving Switzerland.

We'll leave Switzerland officially in November, and I'm thinking of postponing the 2nd and 3rd pillar cashing out activities to 2016. Since my understanding is that I'll need to declare this on my US Tax declaration and pay US taxes on it.

Any tips on this? Specific questions are:
-is it worth waiting to cash out the 2nd and 3rd pillar accounts?
-is there any advantage to waiting to transfer the 2nd pillar to the "free transfer" bank account? It seems that in my case it could just stay with Zurich insurance for a few extra months easily.

Thanks for any advice!
