There are always new tools coming out of the big tool manufacturers. DeWALT is no different - they've recently released a new 20V Max tool line with new batteries and all new tools.

I was just reading a review on one of the first items in their line - an impact driver that sounds like it's pretty powerful and useful. Check it out if you don't know what an impact driver even is - it's interesting reading.

UPDATE: I just saw another review for the other impact driver they released. It's a 'brushless' driver, which means it's got a different kind of low-friction motor. Cool!
