I really don't think they will make plain box logo tees. I don't think I'd buy one regardless because its too plain and probably not worth the money.
Everyone has their own swag, but I dislike Supreme's recent designs, especially for t-shirts. They've gotten whack, but the box logo is one of my favorites. Clean, simple, and a great representation of Supreme.
There seems to be a bi polar crowd though, those that like the simple clean cut tees, and those that like the loud branding.
