AQ claimed to be 90% ready for the big attack just after the train bombings in Spain. That being the case, they are now ready. The transit has come and gone. The G8 is going on now. If they do not strike this week, they have either been stymied by counter terrorist efforts, or they have been conducting a rather successful psyops campaign. And if they do attack this week, but do not use either a dirty bomb or mini-nuke of some kind, then they do not have them. IMHO : >)
Re- timing. I agree with you on this, but the "secret plan" posted 2 days ago refers to the 17th and also mentions June 20 in an ambiguous manner.
