There is no reason to think that it is not a go.
You could try to PM "hotel22bravo" to confirm it.
I would say it's probably safe to plan for this match actually happening.
As far as I know, this match will be using the BC Multigun League rules. There is more info about these rules on some of "John in BC's" postings regarding the 3gunmatch in Terrace BC june 13th.
