What I'm expecting?

Substandard vocal performances combined with more energy than last year in general, but still mostly Jon gripping the mic stand (and maybe tapping his foot at the same time, if you're REALLY lucky...).

EDIT: Basically something like this, at least for the most part:

And if Jon really, really, REALLY gets into the mood, you might even get this level of vocal epicness:

I mean, the guy hits not only one, but TWO of the high notes - during all the four choruses combined! Wow, his voice is back...

Wards.

Got it? It's going backwards (declining), hehe...

Not really.

Honestly, I'm expecting Jon to improve vocally at least a bit, basically continuing the progression he was showing during the SA leg (especially in Rio and Sao Paulo). He obviously won't come anywhere close to any of his pre-WAN tour levels, but I honestly wouldn't be surprised if he managed to get THIS voice back and sustain it to some degree of consistency, at least:

There definitely are some obvious (+ some less obvious) bum notes, but overall his tone still sounds decent and he doesn't look like he's having a heart attack either.
