It is possible that they purposely fell short of demand at launch. That creates lots of buzz. It is also possible that they're still affected by that intended shortage at launch. At this point though, they are certainly trying to get as many units as possible into retail channels. There is no hype to build right now, just sales to lose.
There is a reasonable chance that they will purposely be short at the beginning of the holiday season. I think it would be smart to sell out early on Black Friday weekend in the US. That gets you lots of mentions in the news. But, you need to stock all retailers back up by the next weekend, so that you don't lose many sales to XB or PS. Maybe keep it tight for one more week, but have enough supply that parents figure they'll be able to find one before xmas. Then, make sure there is plenty of supply for the last 3 weekends before xmas, so everyone that wants one can get it.
