This "big announcement" obviously has to do something with sportscar racing. "GLOBAL" can only mean FIA-WEC + 24h Le Mans IMHO. This would further be a logical explanation for NISSAN's recent exit from the DeltaWing project.
With NISSAN developping hybrid powertrains, what is the logical choice then ? It MUST be LMP1. That would be great news for the future of FIA-WEC. Another constructor entry in LMP1 and direct competition for Toyota. Japanese fans (but not only) are going to get crazy about this
