Wii Basics. >.< Since it's not a question and isn't really open for disscussion.
My awnser, would be YES. They are just saying "Launch Window" becuase they don't want anyone complaining. It's like "This kills 99.9% of germs" it most likley kills 100% but they just say 99.9% so if SOMEHOW for any reason, it dosen't kill all of them, they won't hear complaining. Average of 15 Wiis per store, about 2 million at launch throughout NA. It is really a safe bet you'll get one.
