Very good observation. I asked the same question a couple months ago. The answer: FINA is most likely going to 10 lanes in the 2012 Olympics and as such Omaha is planning on going with a 10 lane course for 2012 Trials. Which means there will be 20 blocks (10 from each end since the 50 starts at the far end).
FINA has used 10 lane pools since the Seoul Games in 1988. If you look at all the olympics since then, plus the World Championships, they have all used 10 lanes.
The U.S trials went to 10 lanes at the 2004 trials. 10 lanes isn't anything new for the Olympics.
