Agree in general with all that is said here. 42.2 is good for a faster game, with sharper sculpts and generous pieces for $42 price than the 1941 version ($14) 1941 board ripped in half by toddler.
Anniversary is different. That is it main selling point (@ $80). It has some of the features of global, most of the full unit set, and can be played in a reasonable amount of time.
Speaking to Tourney play, Greg said that while 42.2, Anniversary, Classic and G42 events would remain, that the wider availability of Anniversary could create an Invitational division, where the final winners of Gencon, Origins, Battle of TN and 2 wildcards from the other tourney winners would all play in an upper ladder.
42.2 is the largest tourney draw, then classic, then g42, then anniversary (4-6) boards. That can change now, since before most people didn’t even have the board.
