So how much of TMNT does Viacom/Nickelodeon/Paramount actually have control over?

So the whole thread about Nicktoons starting to air the 2003 show had some interesting posts, someone said Nick does not actually own the 1987 cartoon. Which lead me to consult Wikipedia, this is what Wikipedia had to say about it:

The series itself is owned by Wolf Films, with home entertainment rights residing with Lions Gate Entertainment, and until recently, syndication rights belonged to Nickelodeon's former corporate sibling CBS Television Distribution.[citation needed] The initial five-part miniseries (retroactively considered the first season) was copyrighted by Playmates Toys, although their rights to those episodes were bought out by Fred Wolf Films.

Which I found interesting, here's what it says on the other TV shows:

The second animated series (2003–2009) was a co-production between Mirage Studios and 4Kids Entertainment. Nickelodeon's October 19, 2009 buyout of the TMNT franchise included an approximate $9.75 million payment to 4Kids to terminate its right to serve as the merchandise licensing agent prior to the scheduled expiration of the representation agreement in 2012.[7] Due to the buyout, all future TMNT film and television series rights are owned by Nickelodeon.[38]

Here's what it had to say about the movies:

The first two films were copyrighted by the UK-based Northshore Investments, who according to the legal indicia for the comic book adaptations of those films, owned the supporting characters Keno, Tatsu, Chief Sterns and Professor Jordan Perry.[42][43][44][45][46][47][48][49] The third film was copyrighted by Clearwater Holdings. The fourth film was produced by Imagi Animation Studios, and released by Warner Bros. Entertainment in association with the Weinstein Company.

And finally the comics:

Eventually, due to the difficulty of keeping track of everyone's rights, Mirage made TMNT character creators sign retroactive work-for-hire contracts. One creator who did not sign over the rights to his TMNT work was Swamp Thing veteran Rick Veitch.[50]

So if I understand this correctly, aside from what was created after the buyout, all Viacom owns of TMNT is the 2003 series, the majority of the comics and (possibly) the toyline? Am I missing something here? Is Wikipedia a reliable source on this? How much can Viacom pull from the parts they have little or no control over, without risking copyright infringement?
