I posted this in another thread but it's probably more appropriate here now.
Quoted from jeditemplearchives.com concerning the new snowspeeder:
"LUKE SKYWALKER'S SNOWSPEEDER - In stores Aug. '10
The new snowspeeder was first announced in a September 2008 Q&A session with JTA , and the staff here has been eagerly awaiting it ever since. This new version is scaled much more like the vehicle in THE EMPIRE STRIKES BACK, which interestingly enough is actually SMALLER than the vintage toy that has been the basis for several modern era reissues. The new mold also features projectile firing cannons, stabilizer flaps and two interchangeable harpoon guns. One harpoon gun is movie accurate and the other features a firing tow cable for play with your AT-AT walker. "
