We won't get any dev news even this week, they're probably saving the beta announcement for EGX (or whatever it's called) next week.
Even there we'll get just beta announcement for 2.2 and a recap of its features.
They have nothing to show for after 2.2, they will probably begin to work seriously on 2.3 only after the release of planet coaster.
I can add that, from their last stock exchange report, i guess they don't plan to cash in with season 3 before their next financial year (june 2017), so depending on how defered incomes work (i have no idea), we might get s3 preorders this Christmas,with a june 2017 release, or preorders on june 2017 with a december release.
So 2.3 might be as late as next spring, or worse.
