Well, when you do the math 60KB per second works out to about 5GB per day and assuming it was consistent you may have had a shot at playing on Sunday if you started downloading as soon as you got the e-mail. As frustrating as that is just keep in mind in a month the game will be out on physical disks and you can start playing in a month. With so many games out now there's bound to be something out there to keep you busy until then.
I would check to see if there are any better/faster Internet Service Providers in your area. If not that defiantly sucks.
