I don't recall spitting, punches, and firing of wives being involved in Portnoy's exit, though...LOL. Plus there's this whole Scott Rockenfield legal thing still percolating.
Could I see a limited-run mercenary reunion tour in Japan for quick $$$ someday, like what Dokken did a few years ago? Maybe. But an actual long-term reunion seems nigh impossible to me, and the last 3 LaTorre albums are so much better than all the Tate-era Queensrÿche after Promised Land that I'm not sure what the point would be.
It is true that the 2010-2012 period was horrible for Queensrÿche, mostly due to Geoff Tate's business decisions (i.e the Cabaret and relying too much on outside writers) and behaviour, as you have exemplified. So something had to change and I really enjoyed the self-titled album.
Unfortunately, Queensrÿche, once the "thinking man's band", has gone stale creatively ever since (in my opinion, they have kept releasing generic albums), not to mention the fact that LaTorre tends to make it "his" band, but I guess that's because there is no other strong "media" personality in the band now.
Though, realistically, I cannot see Geoff Tate rejoining QR... unless Chris DeGarmo and Scott Rockenfield do too. But in the former's case, it is rather unlikely.
PS I rate
Hear In The Now Frontier above anything with LaTorre, as well as
The Warning, so I rather "get" why DeGarmo left - the album was his brainchild. Just check the
setlist for the '97 tour, as far as I'm concerned, it was their artistic peak (not commercial one of course). Having said that, the worst albums, in my opinion, are
Operation: Mindrime 2 and
American Soldier, which corresponds to when Geoff was all-powerful in the band.
