Why isn't anyone selling the 32GB Moto X besides on Motomaker??

What's up with retail stores only having the damn 16GB version? Best Buy has 16GB for $49 now (on contract obv). I don't care about a custom color, I'd take black, but I wish they had the 32GB at retail for like $99 instead of having to pay $149 for a custom 32GB on the site. Anyone know if retail is going to get the 32GB or is that going to be Motomaker only?
