Death Stranding Hint?

A tweet from Hideo Kojima shows off his workspace and mentions his love for Kitarō. As noted on ResetEra this includes what looks like some concept art. A closer examination of this drawing of a futuristic craft shows it appears to say "BRIDGES" on the side. This has inspired speculation that it is a hint about a sequel to Death Stranding, or perhaps some sort of DLC, since Bridges is the name of a conglomerate featured in the game.
