Toyota has the best hybrid in the business and it will be even more powerful next year. With the ACO trying to ensure equality with both fuels (porsche is petrol remember), there shouldn't be any more of the bop issues if its done right. So that leaves it down to reliability, hybrid power, efficiency and aero. Porsche I cant say where they will be nor Audi and Toyota. My guess is Toyota will have the aero and hybrid advantage and possibly tire life. Audi will probably still have the power advantage.
