Looks like a new issue of L3W is coming out this week. At the rate we're going, we should see issue 5 cover-dated October. I'll do just the previewed pages on Newsarama here, then on Wednesday I'll copy this and finish up the rest of the issue.
Keeping my Annotations notations, the three Legions as L1 (Pre-Crisis + Lightning Saga), L2 (Post-Zero Hour), and L3 (Post-Infinite Crisis). The "Glorithverse" Legion I'll call L1.5 should we need it.

The Legion of Super-Heroes call in the reinforcements against Superboy Prime and the Legion of Super-Villains as the Crisis of the 31st Century continues. While Superboy Prime comes face-to-face with the last of the Green Lanterns, Brainiac 5 and XS attempt to ignite an electrical storm using the lightning rod, which is destined to turn the tide of the war. And what are Polar Boy, Dawnstar and Wildfire up to in the 20th Century? DC Universe | 40pg. | Color | $3.99 US On Sale February 4, 2009
Cover A (full): L1 Cosmic Boy, with images of L2 in his right hand at top and L3 in his left hand at bottom
Cover B (sliver): looks like a closeup of Universo's eye, reflecting L1 Shadow Lass, L1 Mon-El, and a Green Lantern symbol
Panels 4-8: Looks like the body of Rond Vidar is dead. Beyond that observation I can't say anything else for certain. The guy with the mohawk is Sodam Yat, a Daxamite from the 21st century who was a major player in the Sinestro Corps Wars.
Panel 16: Obviously we've missed a lot between the Sinestro Corps Wars and now.
Panels 1-2: more references to the Sinestro Corps War. Brainy also cured Mon-El's lead poisoning, though it did wear off in a post-Crisis story that may or may not still be canonical (Legion v3 #23).
Panel 4: Mon-El was in the Phantom Zone for 1000 years... oh wait, he just said all that.
Panels 4-9: that's a new version of the Green Lantern Oath, reflecting the wars with the other colored Lanterns.
If only the first 3 pages had more Legion stuff and not as much GL stuff...
Ah, that's better. I'll try to take it left to right, top to bottom. All are L1 versions. None of the civilians are recognizable. (thanks to Shadow Kid for some updates)
