Retailers worldwide are now accepting pre-orders for Portal 2. Several stores are offering incentives so you'll reserve a copy with them.
The exact deals vary from retailer to retailer. GameStop, for example, will give pre-order customers a $5 discount and access to exclusive skins for the two player co-op characters Atlas and P-body. Steam's offering the price cut as well as a free copy of the first Portal. Amazon will give you a $5 credit.
Other retailers haven't updated their site with the promotions yet but they're probably comparable. Might be best to wait a day or two so you can choose the best package.
Portal 2 is being developed for the Xbox 360, PS3, PC, and Mac. It will ship worldwide the week of April 18th.
