While the WWE brands have been split up again, there are still plans for RAW and SmackDown to cross over at Survivor Series next month (this was confirmed during Crown Jewel). However, the commercial for the event also confirms that NXT Superstars will be involved somehow.
This does make sense, especially now that NXT is airing on the USA Network and considered its own brand similar to RAW and SmackDown.
It's highly unlikely that NXT Superstars will be battling those from the red and blue brands but PW Insider claims that there's talk of doing a WarGames match during Survivor Series. On last night's episode of NXT, the first-ever all-women's WarGames match was confirmed for the TakeOver taking place the night before Survivor Series so it could be the men's one we see on this show.
