The debut footage will be astonishing, of that I'm sure. If they can't manage a solid presentation, with this much time and care put into it at this point in development, the people managing this really are incompetent. Even bad movies can have great trailers and preview footage.
I'm not too worried about the lack of hype - many movies come out of nowhere to have huge buzz right before release. And we still have five months until the (alleged) release.
For the record, I have a raging boner for Cameron movies.
