I also only ordered one, and I did it pretty close to the deadline.  I never got any of these postcards people were talking about, so I was getting worried, but my Eopie arrived today.  I'm very pleased - money's been a problem lately and I haven't been buying Star Wars stuff, so getting something in the mail that I already paid for a long time ago is quite a treat.  It's an extra bonus that I never got the Evolutions Qui-Gon, and this one is an improvement over the original.

Well, what I've seen in person (just the Legacy figures, not the Legends, which are also paired up this way) includes:

ESB Boba Fett with R2-D2
Imperial Scanning Crew with Clone Commander Deviss
Rum Sleg with Darth Sidious Hologram
Leesub Sirln with Jawa & Security Droid
TPM Obi-Wan Kenobi with Gungan Warrior
Clegg Holdfast with Jawa & WED Treadwell Droid
DS2 Luke With Concept Ki Adi Mundi
Han Solo (with Stormtrooper helmet and chestplate) with Chewbacca (with headset)

...and some others I can't remember exactly that included TPM Padme, Evolutions AOTC Padme, shirtless Maul, Hrchek Kal Fas, Biker Scout, and Han and Luke in Stormtrooper armor.  And these aren't always paired up the same, but most of what I've seen is generally the pairs I listed.

What I haven't seen but have heard of:

Giran with Ewoks
Ugnaught with Nikto Gunner
Slave Leia with DS2 Luke
Saleucami Trooper with Major Panno
ARC Trooper with Nien Nunb

The quantities have varied, but I've visited six or so Targets in Western Washington and all had at least a few of these.  I'd be happy to help someone out if I can find what you're after in exchange for some of the ROTJ figures.  Prices and distribution have kept me out of the game for months, so I've been really excited to get caught up via these sets.

This is actually a current question on the Wii's Everybody Votes Channel.  I voted for OT first.  It should be interesting in a couple days to see whether the masses agree with us on this one.

Loose would be wonderful - that's how they'll look eventually when I get them anyway!

We're all counting on you, Sal.

I've read elsewhere that that picture is of a prototype; the one seen here is the real toy.

I had a great trade with Michael - everything arrived perfectly and he really helped me out getting what I needed.  I fully intend to trade with him again in the future!

I think the lithographs are all Megatron, so everybody'll have the same story there.

However, people won't have the same story as you with the toys.  I hit my local Best Buy at opening and they had maybe 8 toys total (presumably four of each).  I was lucky enough to get the Ratchet I was after, but I bet anybody who arrived after 10:10 or so was in for a disappointment.
