All of this looks amazing but I couldn't find anything on the one thing I'm after. That's news on beta testing. I understand that an alpha version is made but will public beta testers be able to test terraria 1.4 on console platforms? Really I'm just looking for a way to play 1.4 on my PS4 as soon as possible
No plans to do this for a few reasons - one of which is that historically the public beta programs on consoles are mostly reserved for new titles or paid DLC. Ironically, being a free update puts us outside of the mainstream policy there.
Also, again, no plans to open up those floodgates - so we aren't going to ask for an exception.
