To venture an absolute guess I would say fall.

They take a month off for summer as is normal in their country/region.

I would also expect it to be on the test branch for about 3 months give or take.

I doubt they would put it on the test branch and go off to vacation.

So with all that in mind I would think, if ready, they will put it on the test branch as they return from vacation. This will let them tinker with that while they get the vacation cobwebs shook loose.. then do the release about 3 months from there barring any major issues.

I may be over estimating times a little but I think it is reasonable to hope for this in the best case.
