It will be in the ballot on Nov. 2008 for a bond. Since California is in a huge deficit right now; there has been oposition to this. But with gas prices only rising by November hopefully people will see that HSR is a very viable way of transportation.
I have been to the Accela express in the east coast (Boston to NYC), and while they use older TGV models, their speed is maxed at 120mph, with average speed being about 75-80mph, due to urban restrictions on the route. Unfortunately it is not much faster than taking a bus. If that train was going at 200+mph, it would have been hugely popular.
Addition: With the pain that flying has become, from control checkpoints, lines, to now getting charged for even the first baggage, HSR travel becomes even more attractive. Plus travel with train in California will be very scenic. Virtual tour of how it would look: http://www.cahighspeedrail.ca.gov/map.htm
