It is too early in the game to make large investments in the new tld's.
Most will not survive, and possibly only a few will catch on.
I would wait a while to see what will happen with them.
That being said, NameCheap has a sale, and I think it ends today.
88 cents for several of the new tld's.
Because they were so cheap I picked up a few for a very small investment.
Of course the renewal fees will be much more, but for a low price it was worth the investment even if I do not renew them in a year.
