I think it’s 2 and 3.One of three things is happening here:
1) The graphic is a placeholder that got mistakenly tweeted. There is no internal opening plan.
2) They inadvertently or intentionally got ahead of an imminent announcement about California reopening strategies and know something we don't.
3) They are aware that the state does not plan to imminently change their reopening strategy and are openly putting a line in the sand, especially as reopening now seems to hinge on efficacy of the vaccine rollout.
As I said in the CGA thread, even if the state changes their mind at the last minute about letting them reopen again, I think they will pursue legal action and open anyway. There’s no way any of the parks can survive being shut down another summer. Going more than a year with no clear path on reopening is ridiculous.
