Well, from what little I do know, I've heard that Supersoaker.com will mostly be getting a product listing update at some point, but no real site revamp. Seems like the Wookiee Blaster has already been added.
As for BuzzBeeToys.com, that site should be getting a upgrade for the 2005 season, but the exact release date of the upgrade isn't known (though hopefully sooner than later).
Ok, not much news, but heck, it's all I know. If anyone knows more on these or other sites, please do push up what you can.
