Yeah - I don't think there's much of an appetite to fly players in this year and with so many competitive teams in close proximity - a 'local' all-star team is easy to assemble (even with exams on the go). Not something they can do in other parts of the country (eg. Victoria 2018) and no one wants a repeat of the 2014 Toronto Selects (lost 6-0 and 10-3).
Also, as AUS Fan pointed out - no public announcement in the fall to apply for the coaching position like in the past. So, anyone could be up for this. Gardiner is the obvious 'marketing' choice, but who knows if he has time given his FISU preparations. If he is involved, I could see a few 'special' FISU team members come down to round-out an AUS all-star team.
Regardless - we're getting a rare chance at some bonus hockey we normally never get to see live.
