Those sneaky monkeys at Capcom changed the ending credits artwork between the arcade and console versions of Marvel vs Capcom 2.  Notably Morrigan and Spidey pose for a picture in the arcade version - but in the console version, it's Sakura with Spidey.  Perhaps it was to ease 'fears' surrounding the then-married Spiderman? :)

Anyways, here's the ending art sequence, with the differences noted:

01 the pirate ship sailing away
02 Ruby Heart inspects the Abyss globe
03 Ruby Heart discards the Abyss globe
04 the Abyss globe plunges into the sea
05 Ryu and Cyclops shake hands in front of a crocodile thing
06-Arcade: Amingo, Shuma-Gorath, Sonson and Guile
06-Console: Amingo, Rogue, Sonson, and Guile
07-Arcade: BBHood stands in front of a flexing Zangief and flexing Iceman
07-Console: Tron stands in front of Servbots climbing over a flexing Zangief and Iceman pats a Servbot's head
08: Juggernaut and Jin
09: Anakaris and Doom
10-Arcade: Morrigan and Spiderman pose for a picture
10-Console: Sakura and Spiderman pose for a picture
11-Arcade: Guile, Captain America, Captain Commando, and Gambit
11-Console: Guile, Captain America, Jill, and Psylocke
12: Wolverine and Hayato
13-Arcade: Magneto and Akuma
14: Cable and Ruby Heart
15: the pirate ship sails into the sunset

Most of the changes make sense as regards promoting more commercially important characters.  I do find it interesting that the Magneto and Akuma artwork was apparently left out of the console ports. :)
