Hi all, I came across this today. It's a new product called the Sawyer Squeeze Water Filter. It is a filter unit about the size of an Aquamira Frontier and comes with a mylar type bag. The filter can be separated from the bag and used on any standard bottle thread. Also of note is that water purification tablets are not needed with this filter (so they say).

The filter won best in show from GearJunkie 2011. Here's a blog review of it (it's the second item on this page):
