@Nock, I quote this from Andy Miller, himself:

Regarding 1.6, not at launch. But as soon as we release the 1.5 version, we will turn our attentions back to the last parts in the 1.6 puzzle, namely roknavmenu, and the build process. So we plan on having a 1.6 version out in a week or so after the 1.5 version. Although there are certain 'external' extensions that will not be compatible with 1.5, we are trying to get all our 'internal' extensions 1.6 ready so from our perspective, the two are near identical.
He is referring to the February 2011 Template - Tachyon. So, if you're itching on that 1.6 template, just have patience within a week or so.
