Might just be the angle or an artifact of the photo (or the earlier renders), but the interstage/2nd stage looks longer/taller than renders over the past years...
(that is, the PLF appears higher/farther from the side boosters)

It looks consistent with the renders on SpaceX’s website.

Two questions:

1) Is that a BLACK landing leg on the left-hand booster or just a play of the light?

2) Are people saying that the FH interstage / 2nd stage is longer than the F9? If so, that's news to me - I thought that the FH and the F9 were the same height...

I think the 'landing leg' you are seeing is a rain bird.

It is real! Look at that @SpaceX  #FalconHeavy 🚀 View from Playalinda National Seashore vista. @NASASpaceflight @lorengrush

It's good to see FH-001 on the pad. Maybe, in the not-too-distant future, we'll be seeing crewed BLEO flights from LC-39A again!

Maybe more knowledgable folks  than me can say: As there is no launch license in place for the FH Demo Launch that I am aware of, what is the earliest possible date from today that they can launch this vehicle?

The FAA has sometimes issued prior launch licenses the day before a launch, even on a weekend.

...and the license might not be publicly posted on the FAA web site until after the launch has already happened (maybe not even then).

So no landing legs yet, huh? Was that expected for the WDR?

They are there. Just white. Look closer in the image from this post: http://forum.nasaspaceflight.com/index.php?topic=42705.msg1765037#msg1765037

It has white landing legs. See THESE photos from Elon.  ;)

So, as she stands right there... is it the most powerful rocket since the Saturn V? Or at least the Shuttle?

Less liftoff mass and thrust than shuttle, but more payload than anything since Energia.

The largest potentially payload to LEO/above since Saturn V.

(And the cheapest to (re)launch hands down.)

Finally, the TE no longer looks small and empty, as it did with just a Falcon 9 on it.

So ... how long has this been waiting on by those here? Good Christmas for you all?

She hasn't flown yet, but...
most powerful liquid rocket since Saturn V (7+mlf).  Shuttle had more total thrust (approx 5mlf for FH v 6+mlf)

Energia was the most powerful rocket since Saturn V and still is. Unfortunately, it flew only two times, in 1987 and 88 and had a LEO capacity of about 100 mT and . More than Falcon Heavy. Space Shuttle could only get 28mT to LEO. In pure payload numbers, Shuttle is more comparable to F9 B5 expendable (not quite but close) than FH. But of course Shuttle could launch payload and astronauts at the same time and return the orbital stage to earth, which is quite some different game than Falcon Heavy.
