Chris,
Yes, the current inclination is roughly 1 degree. The rings open back up to 5
degrees next Spring due to our orbital motion before closing through edge-on in
September. We don't get to see that, since it's lost in the sun's glare by
then. It's all here in this plot that I created a couple months back using
JPL's Horizons ephemeris generator.
