Next year Spider-Man 3 & POTC 3 get a May release.
This year it where MI-3 and X-men 3.
With Mi3 there making a litle mistake with releasing the movie in May and not in July like there did with the first 2 movie´s in The Netherlands.
But for Spider-Man 3,i understand a litle bit that there choose for May and not July. Spider-Man is also normaly a July movie,but July 2007 is much populair.
Also Dreamworks skipt the normaly the begin May (Shrek) or July (shrek 2) release for Shrek: The Third to 21 June 2007. One weak Earlyer on 14 June Ocean's Thirteen.
So May,June and July are there enough movie´s.
In March we have Ghostrider and Bean 2 and in April Rocky 6,beside´s that April is not a good month for a comic (February & March also) and not a comic movie in April is better.
So i should say 5 October 2007 for Wolvarine,3 weaks before Topkapi Affair (Thomas Crown Afair 2),who i expect at the end of October 2007.
In August or September i expect it Rush Hour 3,so mabey Magneto can be coming out in August also. In the second weak of September 2007 we get Born 3. 24 January 2008 with National Treasure 2 against it if National Treasure 2 don´t release on 06 December 2007 but on 10 January 2008. Mabey there can releasd Magneto on 6 or 13 December 2006. Magneto can coming out in the third weak of April 2008 on dvd,So i voted for 13 December 2007,2 month´s after Wolvarine.
