Have yet to get the Hoth wave yet. Hoping tomorrow at the local comic shops.
Done.
Sadly I was stupid and snagged them at the first and most expensive of the stores ($1 more per bustup). Guy was at least honest though, told me up front they got in two cases, two chase per and they were already gone. Imagine my surprise when I got home and found a Han ice version in the Han box

One other retailer had already opened and pulled the chase out of his case as well

The third guy, a shop drewlam told me about actually had sealed boxes. I was wishing I'd bought them there both because they were a dollar cheaper and sealed with nothing missing from his case. Wouldn't let me scope through them either because he said that takes away from other people buying them. Pretty cool notion I thought. He'll be getting more of my business.
I also picked up a second snowtrooper for no particularly good reason. Haven't put them together but it looks like an awesome

wave, the Wampa weighs a ton.
If anyone does locate a snowtrooper or Vader chase and doesn't want it, I'd be happy to have it.
