I'm not sure if this EA's fault. TO me this looks like the game director, or someone high up in Respawn lied to EA that the bugs and performance issues are minimal. There's a video on youtube from IGN, (I actually found the time stamp of it from a month ago from REE)
The director basically says: Yeah EA asked if we need even more time, and I went naaah it'll be fine.
Usually I would say, yeah EA told them to say that, but the game is coming out after Q1 and not even near the end of Q2, which is around June. So this is not even the fact of EA forcing them to release it cause of an earnings call. Somebody's getting fired for this one, but also Respawn keeps making retarded decisions like this - remember when it turned out Titanfall 2's release date was done by Respawn and not EA.
Yes EA is evil, but they been pushing out some bangers these days, and I have to wonder if Wild Hearts is a similar situation where Omega Force / Koei Tecmo just lied out of it's ass.
