The slide teasing 'Clone Wars coming to our game systems' showed...

...X-Wing and Legion, only.
And for those, they mentioned this as a teaser - there wasn't going to be any more formal/complete news on them until Christmas. Sooo...late 2019 or 2020 at the earliest for the new Clone War factions to get released in X-Wing and Legion? Makes odds of those factions in Armada rrrrreeeeeeally low.
Now, of course, absence of confirmation is not confirmation of absence. And just because it isn't "soon" doesn't mean "never". AND just because the Clone Wars as a setting isn't coming to Armada (soon, if ever)...does not mean Clone Wars ships wouldn't under the flag of other factions - Venators for the Empire or Munificents for the Rebels or something like that.
But it does tend to suggest (pretty strongly, IMHO) that - at the very least - we aren't getting any new factions set in the Clone Wars for Armada.
