I'm a sporadic 12" collector.  I opt for the 12" Club every year and buy some of their exclusives like the Man of Asia and Kung-Fu sets. 

I bought the Air Adventurer set and Base Camp at the 2008 Joecon.  That tent, figure and jetpack are just about as cool as these get. 

I've passed on all the other 12" sets since then and in 2006 and 2007 mostly due to buying the 3 3/4" sets in bulk.  Price is also a big factor and I'm hoping they reduce the price of the 2006-2009 sets at a future con.  Last year they were clearing out older 12" sets for dirt cheap but not the AT sets.

I picked up all the Wal-Mart AT figures and 45th repros from the last few years.

I also bught a lot of the 1990s 12" and some early 2000s in stores as they were released.  I passed on the 40th Anniversary sets but was almost tempted to start buying those.

AT sets up for preorder over at the club store.  They are a lot cheaper than I expected.  $34.99 for each of the 2 vehicle sets and $44.99 for the Dr Venom set.  1200 of each set according to Lanny at the Club forum.

I had about 5 MASK toys when I was a kid.  My favorite is the Rhino.  A few years back I repurchased what I had as a kid and a lot of the ones I never had. 

I picked up my last loose Swoop just as the bootlegs began to show up.  Now I would be concerned about buying loose Dinobots because who knows what's original or replacement parts.

No Ross stores up here but maybe TJ Maxx and Marshals will get them too.  I drove right by a TJM today.

Skeletor has a all yellow face which looks nicer than the green/yellow versions.  I'm tempted to buy the 2-Pack just for the new Skeletor head but not at $30 plus.

I opened up the blue Firebat last might and was blown away.  This is definitely an arctic vehicle which is always welcome.  They even put new ski landing gear on the bottom.  I'm going to pick up a few more up at the K-Marts where I also saw them.  Still not sure if these will be used by Cobra or GI Joe.  I may have to customize them with some Cobra decals.

Sounds like they already started to charge some people for Moss Man subscriptions. 
Saw the She-Ra MOC picture on Matty's FB page and it looks like a pass.
