The wording sounds like a threat, but it makes sense because they have a shortage of wii's. I mean what else are they supposed to do, distribute them evenly? Last time I checked they are trying to turn a profit (if you own NTDOY, you should be happy) and the retailers are scrambling to sell dses because they know if they get wii's they will sell them and make a larger profit. It's only a christmas strategy. When I worked at KB Toys when the SP came out, we got t-shirts and we were offered prizes to sell more.
Oh and is this an ACTUAL nintendo policy. OR a Toys R Us policy? Cause this type of stuff usually happens between stores in the same district. I mean I can see your district manager saying, "hey whoever sells the most gets the most....and a pizza party YAY!!!"
