Yeah their E3 conference did end kinda weak. But according to a rumor, RDR2 was supposed to be announced right at the end, it was to be their show stopper. However, it was pulled at the last minute because it featured a guy shooting up a saloon and resembeled too much of what happened in Orlando....
I mean, it seems logical when you think about it. They featured a game twice, and far apart from its debut trailer. Just plain coincedence? Who knows!
