It looks like tha Canon EF-S 55-250mm f/4-5.6 IS II lens that was announced outside the US last month will also be coming to the US.  Canon USA has the lens listed on its site.

The lens was previously slated to be available in the UK this month.  No word yet on pricing; however, the existing version of this lens runs around $180 street at the time of this post.  Check availability for the new lens on Amazon.com.
