if anything, It could just be a title that doesn't have any meaning, But as a way of saying this is a new TMNT based on the 87 series, But with a modern twist. The original series had the 80s aesthetic, and this movie could apply a modern day twist to the whole thing, Lots of things will still be recognizable in the designs, But made to look as if they are current times.

No one wants an adult version of the 87 series. A new version where they're adults maybe.
