I don't think it will end up being vaporware, but I do think it will end up like Duke Nukem Forever.

If you're not familiar with that tale: in the mid-90s Duke Nukem 3D was one of the biggest FPS games, and the developer was lucky enough to be independent so they kept most of the money from sales of it. They then used this money to independently develop the sequel: Duke Nukem Forever. It was going to use the Quake engine to be in full 3D, but then Quake 2 came out and they switched to that engine, then better engines came out and they kept switching. Without a publisher to force them to release they just kept re-building the game with more and more features on newer engines.

Eventually their hoard of money ran out and they went bankrupt. Their assets were bought out by another developer who took the work that had been completed on the latest iteration, quickly slapped it together into a semi-cohesive but shippable game, and shoved it out the door. We got Duke Nukem Forever in the end, but as a shadow of what was promised over the years.
