A French website, PC Inpact, has posted the official Microsoft product change request forms for Vista SP1 and Windows XP SP3.

Well, according to them, we will be seeing Vista SP1 a little earlier than previously anticipated:

Windows Vista SP1: February 18th or 19th *BZZZZ*, WRONG! March 18th or 19th, perhaps.
Windows XP SP3: March 23rd or 24th
