Still some dates to be announced, per the blabbermouth article. I'd be shocked if there wasn't a few Mexico shows included in this NA tour. And hope is certainly not gone for additional dates in western Canada and the southeast US, although I'm the people living there aren't expecting any dates at this point.
There's a few days between the Cincinnati and Chicago shows, so a Michigan/St. Louis date (or both) could be possible there. There's also several days between the Denver/Los Angeles shows and the Los Angeles/Portland shows. Good chance for a San Francisco date or a Texas show as well. And with the last date listed as Seattle, there's always the possibility they could hit up Vancouver or other western Canadian cities following the show in Seattle.
I feel bad for the people in the southeast US and Texas, because there's not really any openings in the current dates where they could book shows in those areas, but what do I know? I'm just speculating with no facts or sources to back it up.
