Unless you've been living under a rock, you'll know full well that The Game Awards is right around the corner. On 6th December, Geoff Keighley will walk on stage and kick off his show, which combines the glitz and glamour of an awards ceremony with the relentless announcements and reveals of an E3 press conference. It seems like the show is pretty stacked in terms of the latter -- even Rocket League is getting in on the action.
According to the above tweet, you'll be able to nab something called Twitch Drops related to the car/football crossover, but it also points towards "what's next from Rocket League." That probably just means the next content update; perhaps a new mode, some new arenas, that sort of thing. There's a slim chance it could be something more substantial, however.
We'll find out exactly what Rocket League has in the pipeline soon enough.
