Saying something "really" is limited is not the same as saying we will only be doing one run. In fact, it was pretty clear when Toys R Us got additional stock after the initial sell-out in December that there have likely been multiple runs already. I really don't get why people are so concerned about this. All of us have our copy and paid MSRP or less, so who cares if other people get the chance? Would you not have purchased this if you knew other people would have the chance to own it too? Totally ridiculous.
I think there were initial reallocations of stock or an extended run when they saw the preorders sell well. Who knows how long it takes ToysRUs to move items to stores. I agree that there really is no legal definition for limited, but this was definitely marketed by Nintendo as "hurry get it before it's gone" more than any other game in recent memory.
And yes, as a CAG I probably would not have bought it at launch if it didn't appear limited. I would have waited to bargain bin it at $10 or less. Great games, but been there done that. The "collectibility" of it is the main reason a lot of people bought it.
