I mean, they've already hinted at the Crisis on The Flash. It's hard to say whether or not this will include Darkseid, but I'd say it's a fair bet that Barry will sacrifice himself at some point to combine the multiverse. Which could definitely be interesting for Cisco as he may be the only one to remember the original multiverse.

i think they would go with the Anti-Monitor instead of Darkseid as the Destroyer of the Multiverse.
