Requirements for the theory of everything

In order to form a theory of everything, Lisi's model must eventually predict the exact number of fundamental particles, all of their properties, masses, forces between them, the nature of spacetime, and the cosmological constant. Much of this work is still in the conceptual stage—in particular, quantization and predictions of particle masses have not been done and the model at the moment cannot reproduce all the known particles.

Let me add one thing, the theory of everything must be something a fairly simple vacuum can implement. The theory of almost everything posits the existence of a finite, slightly asymmetric vacuum. Do that and its a lot easier. M8 Theory is another symmetry, a flat space theory. I doubt it.
