We aren't sure what the numbering for the next build will be, but I feel pretty sure that we aren't talking about 1.0 being the very very last final build that we release. 1.0 may be the next release, or it may be a release 9 months from now, who knows. We don't right now, but why worry much about that - we're busy trying to test out a few big new things and working on new content.
