Not sure who is the moderator/wiki manager, but please add a category for the "Prestige" card when you have a moment. Housekeeping aside, I called yesterday and here were the offers:

$200 credit for spending $4000 per month for 3 months
$175 credit for spending $4000 per month for 3 months

15,000 ThankYou points for spending $6000 over 6 months

4 additional ThankYou points for travel (hotel, air, car rental, travel agency) up to a max of 35,000 over the next 6 months

Since I have significant travel spend coming up over the next 3 months, I happily took the last offer.
