Eaglemoss Collections will be releasing versions of many (65) Star Trek ships starting this fall too. According to this article: http://toynewsi.com/news.php?catid=12&itemid=20438
the ships will be fully metal with extremely detailed paint application.
They will be of a similar size to the Hot Wheels ships but more expensive (not by much, the article and Eaglemoss website imply they'll be around the $20-$25 rangewhile Hot Wheels' are $15-$20).
I'm going to get the two or three series released by Hot Wheels (that's how many series were released in 09-10) and some of the Eaglemoss ones.
