I think the finale will be decent. I think Cyclonus is gonna have one-shot level development (which this series can make interesting). I think that's fine though since the Council has really just been sending out Bots and Cons to do their dirty work and Cyclonus not showing his face until now makes sense. As much as everyone just wants him and the Council to hurry up and appear, remember that the Autobot majority of Cybertron are only aware that sometime before their birth, the Great War destroyed Cybertron and its current day survivors (especially its symbols of power such as Optimus and Megatron) should be feared as they caused a whole world to be destroyed. They also believe Decepticons are either criminals or few in number who choose to call themselves Decepticons. They're unaware that the High Council is being controlled by Decepticons. Cyclonus and his group would probably want to hide their presence until they can spread Cyclonus' mind control to all of Cybertron (which they obviously succeed in due to the Cybertronian invasion attempting to spread his power across the universe, starting with the 2nd most frequented planet by Cybertronians; Earth, in the finale) and that's why they've relied on Jazz, a bounty on Bee's head, the Activator Mini-Cons, Soundwave, and Steeljaw's Pack. Politically, it makes sense since their role in the Council is a secret and I'm sure they'd wish to never be seen until they conquer the universe. The only reason we're going to see them is because Optimus and his "All-Stars" warned the Bee Team and now they're going after the Cons. Everybody keep that in mind when wondering or complaining about why the Council won't be seen til the finale.
