Serious question but are we still really expecting an Armored Core game ? In 2019 ?
I know there has been some claims it has been in dev for years now. But what if From never found the magic recipe to make it palatable to the mainstream after all and decided to silently shelve it ?
AC was their best performing IP before Souls came along I'm pretty sure (hence the 900 sequels). Plus, AC5 sold quite well in Japan (first week at least) so it's not like the series was in major decline either.
It doesn't need to hit Souls numbers to be a modest success. Hell, From was trucking along for a good 15 years before Souls hit without any "mainstream" success.
