I think it would be great if next time, when they present the new 5 the give the exact date he will be added to LT. This 2 weeks indication is a bit vague…
Since this is the first time it’s impossible to predict - it basically hinges on what they meant by “when the character was introduced.” Is it the start of the event? The end? The Thursday after? It could be any of these things. After this time we’ll know more.
Two weeks from the start is tomorrow - I think that is the most likely but it could be either of the other two.
Still one a month or less. Thanos was released before December 23. Black Panther would’ve been released around the end of January or beginning of February. Dr. Strange was released before November 6. It is a bit confusing tracking release timings lately. For a while it was one 4 and one 5 star a month. Now it looks like its back to two 4s a month and one 5 star a little over a month.
Generally we get 2-3 4* releases between each 5*. In this case, since they released a 4* the week after BP, I suspect it will be at least 3. So I would say yes, late March.
