If this is the case, I don't understand why I was told at more than one store (a Gamestop, and multiple EB locations) that it had been discontinued

Unfortunately, the employees don't always know what they're talking about. A similar situation happened with the Mario Dance Dance Revolution game on Gamecube - lots of stores sold out, and started telling customers the game was discontinued. Nintendo finally cleared up the confusion and stated that stock was just short and wouldn't be replenished for a few months.

Another possibility is that the game IS discontinued in the sense that the retailer no longer wants to stock it, but that seems less likely than a case of misinformation to me.
