No, the standalones sell out in minutes. The only things left are the bundles.Anyway... that create some questions.
MS doesn't seem to want to sell standalone Series X... instead seems like they want only to sell Series X Bundles or Series S.
Diablo Bundle seems to be avaiable to preorders in big quantities.
Series S already failed and reached a wall in sales.
I gues they want to eat the loses with the increase in BOM of the console with bundles.
