Hopped on over to GameStop today, and sure enough, Dual Pack was in stock. As anticipated, it's nothing fancy -- just a simple bundling of Powered Up and Maverick Hunter X for $14.99. Here's what it looks like, for those curious:
Content-wise, it pales in comparison to the Japanese Value Pack; no bonus soundtrack here. Nevertheless, Dual Pack succeeds in being an ideal purchase for PSP owners on a budget, or if you haven't had the chance to play these two amazing games. Unless you're a hardcore compeltionist, the bundle is not recommended if you already happen to own both games.
Before heading out to your local retailer, it's a wise idea to call ahead and make sure the game's in stock. Dual Pack literally shipped yesterday, and may not necessarily be on shelves. If all else fails, it's ready to ship online.
As far as I'm aware, the bundle is exclusive to GameStop and EB Games. Still, it couldn't hurt to scope this one out elsewhere.
