Currently with PTC2, sprites have a priority field to determine the ordering against background layers. With capabilities in PTC3 like Mode7, I would assume that they would also incorporate priorities for all layers. Technically speaking, the DS/i does support priorities for backgrounds, but that is because of the many different modes that have restrictions on various layers (like one mode only allows 2 actual background layers). PTC2 uses mode 0, which is 4 text-layers, but forces ordering with 3 of them, with the console on top, then background 0 and then background one in the back. You can't swithc background 0 and 1. The 4th is the GRP layer, but it does have a priority value to place it in any of the 4 slots against the others.
