  We examine some consequences of the QCD factorization approach to
non-leptonic B decays into $\pi K$ and $\pi \pi$ final states, including a set
of enhanced power corrections. Among the robust predictions of the approach we
find small strong-interaction phases (with one notable exception) and a pattern
of CP-averaged branching fractions, which in some cases differ significantly
from the current central values reported by the CLEO Collaboration.
