A little spoilage, and then a whole lot
slashdot came up with the link to the new trailer to Matrix: Revolutions just a day after Anil's daily links served up a page featuring a great many plot spoilers. (This latter site is currently unreachable for some reason, but I know it was working just a day ago.)
Honestly, after looking at these two, I cannot really decide whether to look forward to the third movie or to despair, since I could not tell from them how many undecipherable "grad school lecture" scenes the thing is likely to have. But I can tell that the second movie's virtual absence of firearms, seemingly sated with the gunplay of the first movie, did not carry over into this one.
