My theory is the powers of the stones is instead based on Origin of superhuman powers in Marvel Universe. If so, the Tesseract is "Gamma" and the Aether is "Darkforce". Loki's Scepter and Odin's staff do have any stones because Lady Sif confirmed that Asgard only has one stone in its possession, which is the Tesseract. It remains to be seen that power is the orb, which could be "Power Cosmic" or something.

The only kink to this theory is Kevin Feige's comment in this inteview, i.e., "''I don’t know when we’ll actually divulge that necessarily, but [Tesseract]'s the space stone."
