Reading that it sounds like Formula E will be the move for them most likely. I like FE, but man I just hope the big wigs in Japan leave the North American side alone and let them make decisions. With that WEC would not be a bad move, however I can see things happening like that in the future.
Man, I would LOVE to see Yuki in IndyCar. My heart would melt as Taku would be a wonderful mentor to him. Still, I want I selfishly want Kamui over in the US, too.
You think there is anyway VW could possibly do anything to get involved? I mean Audi isn't doing much right now outside of DTM, GT3/GTE, and FE. Porsche is leaving IMSA in the GTLM class, I think either Audi or Porsche will do something in a few years. Red Bull and VW have worked together for years in the feeder series. I doubt Ferrari will sign Red Bull, Renault or Mercedes.
Someone will have to step in or Red Bull is pulling the plug entirely. I just don't see it happening though this soon without someone starting to R&D a new engine to be ready for the new regulations come 2022.
