I am very sure than QE2 will be folowed by QE3,QE4.
But still my adviCe is for investors to lock on to inflation figure,it is very critical!
One of the black swan event that could happen is Bernanke quitting..QE3 is the last bullet for him before American clamor for his blood. You have to understand the money need to flow to main street and not stuck in Wall st.
