I binged season 1 of this show over this past December holiday and really enjoyed it. Season 2 was probably even better.

Based on all the interviews the show itself is too expensive and the second season is a clear finale, so while we won’t see anymore “live action” Ted, the plan is to continue the series (set after the films) in animation.

The cast they have is fun so I’d say stick to the past and keep everyone on board, but that’s not the plan.
