Good luck with that, Joey, but I don't see it happenning any time soon.
Whilst there seems to have been some thawing between them recently, and Johnny playing Smiths tunes and generally saying positive things about Moz - the fact is Johnny seems to be engrossed in working on a new Healers record (as evidenced by all the new songs live), whilst Morrissey is about to embark on another solo tour and trying to get his own next album up and away. Maybe in a couple of years, but they both seem at the start of their own projects right now.
There is one slight chance I can imagine that would point otherwise - and that would be if following the US tour Morrissey STILL can't get a record label he might be tempted to do a one-off reunion with Marr, just to use the resultant massive publicity and hype to boost his own solo career (let's face it - if record companies new there was a massive Smiths reunion gig in the offing and Morrissey had a new album 'waiting in the wings' to record and release around the same time, they'd be falling over themselves to offer him good record deals, because they'd be guaranteed massive sales).
But personally I'd hope if Moz and Marr ever got back together it would be for something slightly more meaningful (as in new material) rather than a career-boosting one-off live show.
