I am wondering if the new lens shift capability is going to allow me to point the image downward enough - with the projector sitting right side up. The A-shift vs. B-Shift described in the user guide confuses me. It doesn't really explain the A-shift.
No problems await you. You still approx 35% into the Downward Shift range when the PJ is not inverted

I am just going to give in and order from VisualApex, I just can't wait to get this thing.... Just give me the okay on the projector placement so I can order it
You say "mount" .....is that a wall mount/shelf/Cradle, or an Ceiling Mount for inverted positioning? If the latter...absolutely no issues...so do NOT angle the PJ downward. I seriously doubt you'll have any issues on a standard mounting (...non-inverted...) but I also suppose a few purists will weigh in with comments decrying the use of any Lens Shift (H or V) beyond a mere 15%-20% adjustment.
They'd be right if you have to go into the 80%+ range, but within that parameter your not going to suffer any noticeable ill effects.
Key stoning is different. It only takes a little bit of such to create distortion and light lost on the edges to take hold. A good reason to avoid it's use altogether, and a primary advantage of using Lens Shifting instead.
If anyone's positioning is so wacky as to not allow for the generous Shift capability of the Epson, then I'd have to say make whatever smallest possible change / allowance you can to bring everything within a "doable" range.
It'll be worth it.
