Im somewhat excited about this, so I want to clarify. I know these are questions that you may not be able to answer- but hopefully you can answer as much as possible...
When you say Henkei- is that a continuation of united 2.0 or Henkei 2.0 (merely a continuation of the original line) or a Takara "Classics" line in the vein of Henkei/United but totally separate?
All the characters- What does this mean? Given its obvious the unreleased moulds would be released in any new classics line- are all the united moulds re-released or all of the previous henkei-d classics/or/and united mould pool to release from (maybe/maybe not differing in style/deco)
Where did you hear this from?
And so after considering these various scenarios- Why would Takara release just united in the form we have and end it now?
