Don't get hyped. Most likely it's either Fortnite, new UT (the one that's completely free) or general UE4 improvements. I mean, Arjan is a pretty badass programmer.
Of course if it would be JJ-related I'd be more than happy, but I don't expect or even hope (hop? [rabbit face emoji here because JCF hates emojis and replaced it with question mark blocks]) for it to not set up myself for disappointment.
