I thought it wasn't so much of Yoda being super agile, but more Yoda flinging himself around with the Force. He was beginning to teach it to Luke in being able to hold himself up on one hand, Qui-Gon and Obi-Won can use it to Force Jump or Force Run. But Yoda can dramatically enhance every movement of his small frame with the massive amounts of the Force he controls.
Hence why he needs the cane afterwards and is panting from the exertion of hurling his old body around that much.
But that was my take on it.
As for marketing, the only add where they grabbed my laugh was way back when Spiderman was hitting huge and I saw a blank screen trailer with big white letters talking about the greatest action hero to swing into theatres this summer, then cut to a scene of Yoda igniting his saber. That got me to laugh good.
Honestly, I think the way I would have most preferred to see Yoda fight though, is to sit down, lift his saber slowly with the Force, and then have it go fence for him. Then if Dooku looks to be having no trouble, animate Anakin's lightsaber as well. And Obi-Won's as well if Christopher Lee is up to the choreography.
That would have been fun to see.
