Deadpool appeared both in the live-action Wolverine movie and in the animated "VS Hulk" one, he has been making a lot of cameo appearances in other characters' comics, he has been given a new solo series and two new minis and an upcoming "Deadpool Team-up" book where he is going to team-up with a different superhero in every issue, and the issue with Deadpool's first appearance recently started being worth a lot of money.
I love DP, but it really seems like Marvel has turned him into their newest shiny cash cow :/
