I agree to that it currently shows the current relationship between the two (technically 3) parties being absolutely at a really good stride, and means a lot for the upcoming Mario film for me in the terms of investment. My curiosity now lies with Pokemon, as Legendary is the current holder of the IP itself. While they are focused on a handful of films, they are working with multiple groups and not just Warner Bros. I kind of wonder that in a similar case to how Kong got shifted to WB, they might shift Pokemon to Universal, if Universal Pictures is willing to sink in the money for the IP to be adapted on that side.
Hopefully it also means in Pokemon's case, that it can be in EU sooner than later too.
