Definitely there won't be more shows for this year. No matter in what condition Jon voice is in.

I think there also won't be enough time for them to record a new album, because the big "40th Anniversary Tour" will probably start from February-March in Australia, so the promo campaign should start around the end of this summer or the beginning of the fall.

Right now from marketing perspective I believe the best thing for the band is to not put another record in the next 2-3 years. If it's true that they will put out a new boxset for the upcoming tour that will be something to look forward to, but for a new album, if they want to gain some success they will have to take a couple years break of doing it.
