What if RotS Yoda hadn't left Coruscant?

What if Yoda's didn't have good relations with the wookies and ended up not traveling to Kashyyyk?

B-team amp?
Sheev screwed?
Order 66?

Then Palpatine wouldve been stopped, Mace AND Yoda coming to arrest him wouldn't have gone so well for the Chancellor

Sidious would've blitzed Mace before he could sink into Vaapad and then the rest of the B team and then he would've gone on to defeat Yoda as occurred in the movie and novelization.

He probably would have stopped the assassination attempt before it began.

Yup. Mace wouldn't save Yoda, Yoda would have died. Without Yoda, the Empire would never have been overthrown. A fact which I like, because the Sith are much cooler than the Jedi.

@NewGuy:

Yeah, he did. Here's the exact passage:

In the virtual nonspace of the HoloNet, two Jedi Masters meet.

One is ancient, tiny, with skin of green leather and old wisdom in his eyes, standing in a Kashyyyk cave hollowed from the trunk of a vast wroshyr tree; the other is tall and fierce, seated before a holodisk in Coruscant's Jedi Temple.

To each other, they are blue ghosts, given existence by scanning lasers. Though they are light-years apart, they are of one mind; it hardly matters who says what.

Now they know the truth.

For more than a decade, the Republic has been in the hands of the Sith.

Now, together, blue ghost to blue ghost, they decide to take it back.

In the RotS film Yoda tells Mace not to:

There was nothing there about execution or assassination though. Mace went to arrest Palpatine, then decided to assassinate him after the Force Lightning started.

Palps would have died

Nah.
