Recommend three fast primes for MFT to cover wide-to-tele?

I'm weighing options for a more compact backup camera to my 60D, and I've decided that I want to shoot with primes versus zooms, the reason being I want to take this camera into more indoors venues, and that means speed. My top choice right now is the Fuji X-E1, but a close second is the OM-D E-M5. (The NEX-6/7 is a distant third.)

What MFT prime lenses would you guys recommend for the OM-D if I wanted one wide-angle prime, one normal prime, and one telephoto prime? All at least f/2, of course.
