The Angels are my favourite villain but I'm not sure we're going to see them in the main series as such if they pursue the 'Class' arc. Given that ending, you'd assume that Class and Who will crossover properly for the ending of a giant angel in London (See Angels in Manhattan for the statue of liberty angel) Seems we keep getting varying results though between ones that just snap your neck or the others that send you back through time.
