At this rate I guess we can expect Tiga to release around the time Ultraman Trigger is officially announced?

Maybe? Next on their agenda is all the Zero movies and Ultra Galaxy Mega Monster Battle, set for Spring. Following that, they have announced plans for Tiga through Cosmos... though they've also announced plans for 80 and even Gridman, so it's definitely possible we could see them first.

Still, with this year being Tiga's 25th; I think it'd be a pretty big missed opportunity to not do Tiga this year!

Exactly. And we already know that Tiga is gonna matter greatly this year with the commemorative show somehow, so would not be surprised if Tsuburaya requested their overseas distributors to make room for Tiga.
