This has officially entered MML3 territory for me. And that's pre-DevRoom MML3. I heard so much shit and was hyped every time I just learned to not care and enjoy the announcement when it finally comes.
And just like MML3 even if it is announced I won't put it past them to cancel it.
Watch this be a new IP. The universe is putting significant effort to prevent a new SH game from happening in all timelines. (I'm hoping those rumors are true and if this project ain't that, it's dead)
