inXile and Choplifter are. The former is the company responsible for the amusing RPG The Bard's Tale, the console versions of Line Rider and not much else. Choplifter, for the uninitiated, is a series of video games (first released in 1982) in which players had to pilot a helicopter behind enemy lines and rescue hostages. Also, as a sidenote, it was really fun.
With that out of the way: GameSpot reports that inXile has filed a new trademark for Choplifter, listing it specifically in the category of "downloadable electronic games via the Internet and wireless devices." As such, it sounds like a new version of choplifter might be headed to services like XBLA or PSN. We also wouldn't be surprised if it showed up as a new iPhone title either.
Whatever inXile is doing with the franchise, let's hope the game doesn't stray too far from its roots. A 2D/3D makeover å la Bionic Commando Rearmed would suit us just fine.
