I hope so too, but I'm not counting on it. Health issues aside, it seems Blaze is playing it safe as far as where he goes, likely for financial reasons. I'm not saying he's hard up for money--I highly doubt he is--but I think he and his management are being conservative as far as where the audience is. Gambling on a costly North American tour where there may not be much of an audience left probably isn't the wisest move, particularly when touring costs already are stupidly high for artists.
I mean, the only time I saw him solo was the one time he did any kind of a US tour, and that was in 2011 with a local band he'd hired to back him. Between 15-25 in the audience max. Garbage promotion, no doubt, but I probably wouldn't risk spending that much in case turnouts like that happened again if I were him. Even so, he put on a blazing (pardon the pun) show, and the crowd size seemed to have zero effect on what he put out there.
