Good news Rocket League fans, as it seems the game will be out on SteamOS & Linux before the Xbox One version, and it's looking like it will be end of January to early February.
I'm happy to say I was wrong about it, as initially I thought the Xbox One version delayed it, but then Valve made comments about it directly and it being them holding it up. Now we have a developer on reddit saying this:
QuoteMac version was delayed along with SteamOS release (not because of Xbox One, we have different teams helping with each version). It will still happen early this year and before Xbox One release in February, though we don't have an exact date yet.
They also tweeted this:
@BenjaminArd Mac is not 100% this year, but likely not.— Rocket League (@RocketLeague) December 19, 2015
Upcoming order: SteamOS -> Mac -> XB1
Stuff like this makes me happy, so let's hope there isn't another delay eh!
