We had the last prereleases oct 30/31 and november 6/7. November 13/14 no major tournaments. November 20 starts CC. Cities end January22/23. Sounds like the next set comes out in Feb. So, January 29/30 I'm guessing no major tournaments. Then Feb 5/6 and 12/13 prereleases for the new set which would be released feb 14th. Feb 19/20 no major tournaments. Then states could start on Feb 26.
These are all assumptions based on the last batch of major tournaments. Seems logical to me. Just have to wait and see what happens!
