blizzard ideally need to say Seasons will always be 2 week apart and never earlier.

They had said that…

@Nevalistis

We decided the compromise was to have at least one week downtime between patch deployment and season start. That gives us a more forgiving window to address critical issues, should they arise, and we plan to continue using this format moving forward to ensure we’re launching each Season in as strong and stable a state as possible. It also allows us to provide a more reliable Season start date going forward.

…and they had stuck to that until this upcoming season.
