Ugh, hate to hear this.
Yeah, I seem to recall a lot of the CET strip properties have a lot of these games.

Shouldn't be the end of OBJ totally though- from what I recall almost all of the off-strip casinos have OBJ in the viridian cabinet still, I recall the triangular buttons on those, at least at all the Boyd casinos I have played at. But probably no more OBJ on the strip to play.
