I think we've expected such an attack since 911. I wouldn't be surprised if this year is the winner, but I wouldn't be surprised if we didn't suffer multiple attacks far in advance perhaps beginning by this Friday. It is also possible that the transit of venus (which has a significance to the Jihadist mentality as being significant to Allah) which took place today could be seen as a sort of universal "go code" for action. That possibility was previously mentioned here on TM.
