Exai didn't leak, it was intentionally released earlier by a month, just like Oversteps and Move of Ten
Yeah I know, I just felt like because it wasn't a exactly a month before but a few days after that, it felt like they held onto it for as long as they could before putting it out. I'm probably wrong in thinking this but it was just a feeling, because didn't Oversteps leak before the early release? I'm probably imagining things that never happened... (going days with less than 2 hours of sleep a night is seriously taking a toll on me...)
But perhaps it was a pre-emptive leak because physical production was about to begin? (I've no idea how long it takes to produce all the physical stuff before release day).
