Ehm...am I missing something or why does everyone think they are skipping E3?
They aren't, they said there will be a shitload of NEW information on FFXIV 2.0 on E3 as well as a website afterwards.
NEW as in "stuff we haven't seen yet in the PDFs".

The ONLY thing they aren't showing is a trailer, and seriously, I'm kind of happy about that.
Trailers never really show anything about what has changed, they always look cool even if the game is crap.
If they only showed a trailer, everyone would have been like "Meeh. They are just hyping their broken game with an awesome-looking trailer while the game is actually shit."
By NOT doing that but rather showing information on what has changed and will continue to change with the release of 2.0, they can show way better that FFXIV 2.0 is NOT the same old broken game with only a new wrapping.
