Let's say it's a Dragon-related Game Pack. That alone can give us the date.
February Dragon is a novel by Colin Thiele, and was published on September 1st, 1965. September (9) + 1st (1) = 10. February 10th. Now, that's on a Wednesday. We normally get hints about packs on Mondays, then reveals on Tuesdays. But I'm pretty sure we've had reveals on Wednesdays, too. Regardless, February 10th is suspiciously close to when a pack would normally be revealed.
On an unrelated note, the author's full name has 11 letters. February 11th is my birthday. EA would know about my birthday because it's attached to my all my EA-related accounts. So they could very well be surprising me with a dragon pack for my birthday.
EDIT: The book came out in 1965. 1 + 9 + 6 + 5= 21. As in, the 21st anniversary of the Sims. The anniversary was on the 4th, but we're getting the patch 21 days later, on the 25th. It all comes together.
