That's a pretty high up there possibility too.
Nah. Compile Heart isn't sneaky like that. They always lay all their cards out on the table at these events, and main Neptune games are usually teased but never fully revealed until the rag containing the aforementioned information is released. They might troll their fans from time to time, but I don't see them keeping a mainline game secret. Likewise, spin-offs are usually revealed in their entirety right then and there with an added platform; save for Noire's game.
Might we also add that CDO also doesn't have a platform listed for it, despite the fact the two games it accompanied were revealed to be PS Vita titles. If it's PlayStation 4; which is highly likely in my honest opinion, then it is most certainly not Vert's game, nor a spin-off.
I also won't discredit the idea that this may be something entirely new in the vein of "From the World of Hyperdimension Neptune" rather than it focusing on the girls and the so-called "console war" they still tout to this day. Perhaps it's to be taken literal? Four Goddesses Online: Cyber Dimension Online, the actual game that Vert and the others have played without any outside Neptune influence whatsoever.
They've done it for their other brands, after all.
So there is an; albeit weak, precedence for them to go that route.
