Since this is going to be original (EG not tied into the original Gridman series) I think they'll make references and possibly even out and out parody both series...but still keep it true and fun to the original. I trust Trigger not to stuff this up.
I also hope that this means we'll get an SH Figuarts Gridman as well as all new toys...

I also hope that either they bring back the original music:
Or if they DO change the soundtrack, I'd like them to use the music style of some o f the newer Tsuburaya Ultraman series (And get a decent english singer for the dubbed version!):
