There has been talk scattered in other threads, but there isn't a thread yet. We love the Imaginext stuff at our house. We have huge tubs of Imaginext toys for Dragons, Space, City, Lost World, and DC. The Imaginext stuff is way superior to the JLU stuff - same level of articulation and way more accessories, playsets, and ships!
The Green Lantern Jet was put out last December I think. I think we bought it right before or right after Christmas. The jet was even repainted as a TRU exclusive Robin Redbird Jet over the summer.
That is one of the neat things about the line - all sort of things get re-purposed so there are tons of options. Examples - the city Ambulance was re-used as a Joker Van and is now shipping again as Two-Face's van. The Lost World bi-plane became Riddler's bi-plane. The Ocean World submarine was repainted as Penguin's submarine. Etc. Tons of things to buy!
So far they've made figures for:
Good Guys - Batman, Superman, Robin, Green Lantern (Hal).
Bad Guys - Joker, Penguin, Mr. Freeze, Riddler, Two-Face.
Coming soon are Kilowog & Ch'p (with a GL/Oa Playset), a Flash & Hawkman 2-pack, and Killer Croc too!
