Re: the TIMELINE thread
X-Men (2000), X2 (2003), and X-Men: The Last Stand (2006) are all set in the "not too distant future"
Which means that the film trilogy has to take place sometime between 2007-now.
Where X-Men Origins: Wolverine takes place specifically doesn't make any different to that. But I would imagine, if we're putting specific dates to it, it would break down something like this:
X-Men: First Class - 1963
X-Men Origins: Wolverine (Team X / Africa mission) - 1973 or 1975 (there are 2 prevailing theories on this)
X-Men Origins: Wolverine (bulk) - 1979 or 1981
X-Men / X2 / X-Men: The Last Stand - Anywhere between 2007-2013, but I'm guessing more realistically 2007
The Wolverine - 2013
The Wolverine (mid credits scene) - 2015
X-Men: Days Of Future Past - 2016 (10 years, give or take, after X-Men: The Last Stand - I doubt the movie is going to specifically state "10 years after X-Men 3")
Another theory is that X-Men, X2, and X-Men: The Last Stand all take place closer to present day (2013), closer to the setting of The Wolverine. The mid credit scene takes place in 2015, and Days Of Future Past takes place somewhere in 2023-2025, which would be 10 years after X-Men: The Last Stand, but it assumes that there are only 2 time periods: future (OT characters + Bishop, Wolfsbane, and other new characters) and past (young Xavier, young Magneto, Beast, Mystique, Havok) instead of the speculated 3 time periods. However, it does fit in with the much talked about 2023 time period.
The main trilogy does not take place anywhere earlier than 2006 or 2007 though.
But at the end of the day, I don't think we're really supposed to have specific years.
