I think it works like this;

1.0 CE = CE Items on the 24th

2.0 CE = CE Items on the 27th

I'm a 1.0 CE, and when I activated my pre-order code, it listed all the items, as well my old ones for the CE. Could be wrong. Going to have to just wait for now. Either way, you'll have your stuff 3 days after the EA, so nothing to worry about.
