The initial sets that took my eye was the "The Phantom" and "The Ghost". The reason I noticed these were because I hadn't seen these spaceships before. It turns out that they're featured in the new TV series - Star Wars: Rebels. Both ships include minifigures from the TV series, and both have a very unique look. "The Phantom" looks like a cross between a shuttle craft and cargo carrier. "The Phantom" looks like some sort of personal fighting craft, perhaps in a similar vein as the Millennium Falcon was to Han Solo in The Original Trilogy. I suppose all will be revealed later this month, as soon as the TV series premieres.
The following set I noticed was the Star Wars Snowspeeder, and this I almost purchased for my son. He loves Empire Strikes Back, and we have spent many an hour recreating the Battle of Hoth. This looks great, and I urge you to hunt it down if you're into original trilogy Lego sets. Additionally it is included with Luke Skywalker, Dak Raltor (his gunner), along with a Snowtrooper. The speeder has two spring-loaded missiles, and also a rear harpoon hook/blaster.
If you want to go the whole hog, the next set I wish to mention would be the AT-AT (All Terrain Armored Transport). This also looks like the genuine thing, and you can move the head, shoot missiles (again, spring-loaded), open up the side hatches and set up the trap door Luke uses to ultimately destroy these four-legged walking tanks. This set has five minifigures, of Imperial variety.
Next is the Imperial Star Destroyer. This is one you'll need a spare room to keep in! You can take off top to reveal the interior, including bridge, control room, and more. You get eight minifigures with this - Darth Vader, Imperial Officer, two Stormtroopers, Imperial Navy Trooper, Imperial Crew, plus two new and unique figures - an Emperor Palpatine Hologram and Mouse Droid.
If you really have money to burn, and a spare room to keep it in, next up is the Jawa Sandcrawler. This thing is large, and again, looks the part. It comes with a steering mechanism, working cranes, lowerable front ramp, raisable side panels and heaps more (even a speeder bike!). A true eye catcher, the Sandcrawler includes a wide variety of minifigure,s including Luke Skywalker, Uncle Lars, C3P-O, R2-D2, Jawas, and a few other droids.
The last two I came across were the B-wing, and Mos Eisley Cantina. The B-wing has a rotating cockpit (same as in the movies), adjustable wings, and spring-loaded missiles. Three minifigures come with the B-wing. The Mos Eisley Cantina set looks awesome, and is actually an excellent addition if you are also seeking to include some Original Trilogy characters to your current Lego collection. These include Luke Skywalker, Ben Kenobi, Han Solo (and Greedo - you get to decide who shoots first!), Cantina band, dewback and Sandtrooper.
