I had read somewhere, or at least I think I did, that this is planned as a trilogy. Is this true or am I more confused than usual?
Kind of. The X-Men Origins line is set as a trilogy with Wolverine as the first part and Magneto as the second and the third unannounced yet although rumors are that it was supposed to feature either Rogue or Cyclops and the Cyclops story was to focus on the creation of the X-Men.
Although Gavin Hood said he wanted to do a sequel that focused on Miller's storyline in Japan because he feels its a vital piece of the character's history that wasn't able to be explored to its fullest in this film. Jackman said that he loved that storyline and it was his favorite Wolverine story so if this film does well I wouldn't be surprised at all if both of them got their wish although Jackman's contract I believe would be up for renewal because his last one included X3 and this film.
Are we going to have a Hot Toys Wolverine ?
This is up in the air. The announcement of the Hot Toys license on Iron Man only indicates that they have made a deal with Marvel Studios, which is easier because they only have to get rights from one source. This is a little more complicated with previous releases.
Now, the speculation is that the amount of money that HT paid for the TDK/DC license was way out of the ordinary which is why people think they went after a Master License for all film incarnations of Batman, now since they were all released via WB and DC it isn't as much of a hassle.
If HT did this they'd have to have not only made deals with Marvel Enterprises (the licensing section) but also with 20th Century Fox and Sony/Columbia, Universal, etc. Doable but more of a pain in the ass and definitely more money. It looks like Koto did something similar though because they are releasing a Daredevil film bust based on Ben Affleck that was part of the "No Photos Please" at SDCC.
So depending on how much they put down in general would depend on whether or not we would see an HT Wolvie.
Good news is that Kevin Feige said that no other Marvel characters would be licensed out and that companies would have to work with the heroes and villains they already have licenses for. Rumor is that they are actively getting back some licenses like the Fantastic Four and X-Men series but have recently signed an extension on the deal with Sony/Columbia to allow them to have Spider-Man and continue that series.
