I'm going to guess Seattle, then. It's about a 3-hour drive down the highway from Vancouver, so they'd be able to haul their stuff there with a rented truck (hopefully with a stronger lock this time) in just half a day, and Japanese staff and talents would be able to get there with a direct flight.
I have a lot of questions beyond just "when" and "where," though, and maybe even Phase themselves don't have answers yet. Most importantly, have they brought on experienced staff to run this, or are they going to try to figure it out own their own, I mean gee, how hard could it be? If the latter we're probably be in for a disaster which might be entertaining if you're not a guest or attendee, as amateurs tend to severely underestimate the planning and money necessary to pull these things off. I'm also curious if they really intend this to be a Phase-only thing, or if "Phase friends" might also be making an appearance, or if they'll throw it open and invite any corpo or indie that wants to make it - even if Phase talents get top billing, having other talents, Phase-adjacent and otherwise, will make for a deeper roster.
