Is it worth starting a new campaign right now?

I am expecting at least rebellions, that is something I consider substantial, and maybe children education, even though I'm not expecting it to be substantial, it will probably a very menu interface thing and will not raise interactions, it will feel, just like marriage like a chore to do rather than something to improve your immersion but another things are for example, the improved garrisons mod, diplomacy options, things to do in towns and in taverns, and more interactions between lords, effects that make the world feel dynamic, I'm sure will not be added soon, or at all during development or EA. Basically what we have is what we get, but at least in 2/3 months it will be fixed and perks will be finished

I hope they will start implementing dialogues additionally to what you said

These days I am really itching to play again... should I start a new campaign on beta branch 1.5.5, or do you know maybe if there's another update coming soon? In that case I would prefer to wait for the new update.

To be honest, I'd say just pick a playstyle you've not tried before and fire up a new character sooner rather than later. No one is 100% on when the new patch lands or what it will contain. I find the first 50 days to still be fun no matter how many times I play it. I'm currently playing a horse archer bandit/mercenary and having a blast.
