Ok so it looks like the HARA edition PRO4 just came out. Its not in hobby stores yet....but its out. At least HPI is saying.
So that means the HPI REP I spoke to was well informed and the R40 Hara Edition will be out next month. Possibly early next month.
That means by the end of july. We could be already racing the hara editions.
Here are some pictures of the pro4. Even the box looks cool.
