when are supposed to take effect?

When the new starter comes out, around late October-early November.

what are these new rules you all speak of?

Whoever goes first is only able to activate 1 figure first round, IIRC. So if I win init and choose to go first, I can only activate 1 figure. My opponents activates 2, then I activate 2, and so on so forth...

This will be interesting for the game...

It will make the game MUCH more balanced. I cannot wait.

I wonder if characters like Dodonna or Grand Moff Tarkin would be able to break that rule...

From discussions I've had, Dodonna won't help, but Tarkin might - I'm still not sure about Tarkin, though.

Well based on wizo usual rulings,

Game peices always trump base rules

Dodonna might do it cuz he states " you may choose to activate 1 or 2 chars this turn*

it already breaks the turn rule of # to activate so take it as you will

They might just word the new rule so it can't be modified by any abilities.

SO is their no down side to san hill?

you still only get to activate one every round.....

Dodonna's CE says "you may choose to activate only 1 character in each phase". So that wouldn't work with the new init change.

Tarkin's might work cause it says "If this character has line of sight to an enemy at the start of the phase, you can activate up to 3 characters in that phase."
