Ni-Oh afaik never got a release window back then, so I think the project has been completely stopped early on and for several years, but it's curious they seem to have reawakened it 1-2 years ago, by far most of the stopped projects just never see the light of day (most of those are never announced though).
The original trailer seems to point at a Musou or Kessen like game, which W-Force is known to develop really efficiently, so we probably will see something soon if they really decided to make a game from the concept.
In contrast TLG did get a very rough release window indicating they initially got pretty far into development, maybe even as far as beta, but unsolvable quality and/or technical issues made Sony pretty much hit the reset button on that - maybe even more than once when they realized they should move it to either PS4 or even Morpheus - but it seems it was always in "active development" in some form (team size probably fluctuated a lot) during all that time.
