Will the wharehousing limits apply to just search (aka google.com) or to the entire google network?

Adscense, google maps, utube, doubleclick to be, google-office, gmail, ...

Does google really have to delete the data, or just "anonymize" it by setting cookies to self destruct in a year? Google will obviously issue new cookies so this approach is totally ineffective for anonimizing purposes.

I hope this legislation goes a bit more technical than just placing a duration clause in.
