This is but a personal opinion of mine, but in case the maintenance from the company's side concludes before schedule by quite a time. I see no reason why they'll not launch the early access earlier. I understand schedule is important, but when the chance presents itself to have it much sooner than planned, why not take it? Let people have fun.

Of course, I'm saying this IN CASE the maintenance from the company's side concludes. Otherwise, it should stick to schedule, and this is by no means an assumption that it did conclude.
