Thats because it may not be the ones that are with the highest availability. This game has a 75% or greater likelihood of shipping. Is what high is but it will still be trumped by Very high and Available now. It helps though to have the games you REALLY want in your top 5. Good luck and I hope you get the games you really want.
It take about 3-5 business days. If it take longer then that you should right them, that's what I am about to do cause I haven't received my game which shipped out on 4/1/2013 so I am going to ask whats the deal.
