No and I have no idea why! I talked to Wrobo just before the final Rivalry Series game and sort of off-handed said something about maybe they know the dates, but it's not public info and he laughed and said "We don't know either"
I can't find my tweet about it and I can't remember if it was studio or in game, but someone definitely said "upcoming World Championships in April." I don't know if that was habit, since before the past two years, that's when the tournament has been held. But yeah, we have no info as far as I know.
One thing I'll add to the ECAC conversation is that traditionally, those programs have recruited heavily from Canada. The ECAC has big representation on Canadian rosters, both with players and coaches (and there's an obvious correlation there). The newest USA U18 roster has some girls committed to Cornell and with Rory Guilday, I think we may be seeing at list a little bit of change there.
