Brand of panel aside, if you think you might ever want a whole-house (or part-house) backup generator, now is the time to install the wiring for it. Typically the transfer switch switches to a subset of circuits to keep live (unless you do in fact install a true whole-house unit). Wiring those circuits on a separate subpanel now will make the eventual installation much easier.

I've recommended this to several people, both in blizzard country and in hurricane country, and those who took my advice have thanked me for it.
