Of course you can wait until they drop enough that there is no capital gain.
Or alternatively - if the gain doesn't shrink, wait until 2015 and the removal of a separate rate for capital gains -g-. Choices, choices... .
(Personal note - I would be fine with the removal of capital gains rate if that somehow fixed the Romney/Buffett break. Not because I am jealous, but because it is over-rewarding the wrong segment.)
