Sounds like this news has been pretty well confirmed at this point, as far as 2006 and 2007 for sure being limited to just Superman and Batman "worlds" in the DC Superheroes (6" scale) line. Disappointing, to say the least, but hopefully we'll at least get some good figures from these lines. Aside from what has already been revealed in the first 5 series or so, characters such as Catwoman and the Creeper have been mentioned as well.
Thinking more about this, with this line not being "universe wide" as many had hoped, it really seems like DC really doesn't compete very well with Marvel when it comes to action figures. I don't know whether it is due to Mattel alone or what, but looking over the comics, tv, and movie lines, it just seems like Marvel/Toy Biz has done a better job. Now, once the line changes to Hasbro's hands next year, we'll see how that goes. Although some of Marvel's movie lines do have an overabundance of certain characters, for the most part the lineups have been done very well. Most figures are well articulated, scaled to each other, and pretty accurate. There's always some stinkers, but overall I'm pretty happy with what I've seen in the Spidey, F4, and X-Men lines (although I don't really have any of those). Although I did pick up a Batman and Scarecrow from the Batman Begins line, and plan to grab a Superman and Lex from the Superman Returns line, I don't think that those lines were/will be very well received. Looking at some of the pics of the Superman Returns line in ToyFare, at KBToys.com, and at ToyNewsI.com, they don't look too spiffy overall. Now, with this "comic accurate" figure license being limited to Supes/Bats, its obvious that the DC Superheroes line isn't going to compete with Marvel Legends very well either. I do enjoy the JL/JLU toyline (and show), and they have really offered a lot of characters from there...and it sounds like they will continue to....but that seems to be the lone bright spot for DC in the figure aisle right now.
Anyways, a bit long winded, but I was just thinking about this today. It seems, at least to me, that Marvel is really dominating this area of the comic market. If DC wants to compete, they should really allow Mattel the entire license...or Mattel should step it up in areas like movie figures. I still have hopes that Mattel can get the master license in the future, but that's two years away now at best. With Legends possibly winding down or switching hands, they had a chance to grab some of that market, but that might not be as strong now...especially going into 2007. The Supes/Bats characters will only last so long before they have to start doing lots of variants of the big two. Sorry for the rambling....just a little disappointed in this news for now and it got me thinking about comparisons between the two companies action figure/movie wise.
