My guess with the NorCal dates is trying to figure out which venue to play (Oakland Coliseum, right... ) and when to schedule it, due to baseball, football and any other concert tours around the same time.
My guess...Oakland Coliseum within the first two weeks of November...
I think that Ocotober 28th Vancouver date is pretty firm as being the final 2009 show, unless vancouver gets a second show.
They already are planning June and July 2010 for North America, so I expect those cities to mainly be different from this year's cities. Look at the fairly large markets skipped this year and you can pretty much come up with the places that will probably be played next year.
I can see shows happening next year in cities like Seattle, Oakland, San Diego, Denver, Minneapolis, Columbus or Cleveland, Philadelphia, Pittsburgh, Miami, Montreal, Edmonton, as well as potential returns to some of the cities played this year like Foxboro, Pasadena or Los Angeles and East Rutherford or New York. Mexico City could also occur on this tour leg, unless they group it in with the proposed fall 2010 South America dates.
