Someone left this fantastically snarky comment on my blog which sums up how I feel much better than I can:
It sounds like WDW said they were announcing "dates" and then proceeded to announce "nebulous, vague and lengthy seasons of time," with the exception of July 2012, which although 31 days long, is a beacon of specificity compared with the rest of the announcement. I'm afraid WDW's refusal to release actual "opening dates" will provide no help whatsoever to anyone planning a visit in the next six months, except to discourage those going before July, and cause a lot of others to postpone their vacations until 2013 or 2014. Oh WDW, you always get me excited for a big announcement, only to announce... nothing new. Yet I fall for it every time! ; )
I think it's spot on.
