not true I just checked my bank records and my card was charged from Frontgate on 1/10/11 for that tour which means it was announced on 1/7/11 cause they always go on sale the monday after they announce on friday.
I have high hopes of them doing the same thing this year!
Not sure when they went on sale, but do a google search for spring tour 2011 and there are many sites dated Dec 10-12 with the announcement. Here is one.
