No reason they couldn't have had all the plans laid (and similar ones for other cities) except for the date -- just waiting for the "Go!" signal. Weren't we finding all kinds of plans, subway layouts, etc. when we first invaded Iraq? (Here, too, I think -- on seized computers.)
My guess is the G-8 Summit was the "Go" signal.

I believe they found more plans recently, too.
Prayers up for the British.
If not meant to coincide with the G8, then it probably was today simply because the date (7/7) is easy to remember, easy to use as code, and a bit of pattern, which the stupid fanatic Islamifascists seem to have a fetish for.
