The other day we showed off a pretty thorough hi-res gallery for the upcoming costume DLC for Ultimate Marvel vs. Capcom 3. Now Capcom has prices and release dates for all the packs, including a Value Pack that collects them all in March.
Many of the costumes were available as Pre-order DLC depending on where you grabbed the game, but here's the full rundown of release dates for DLC. Each pack will cost $4 on PlayStation Network / 320 Microsoft Points on Xbox Live, unless you wait for the Value Pack in March.
Nov 22 - Rising Dead Pack (Jean Grey, Ghost Rider, Frank West, Nemesis)
Dec 06 - Evil Twin Pack (Spider-Man, Deadpool, Hsien-Ko, Vergil)
Dec 20 - Ancient Warrior Pack (Hulk, Magneto, Arthur, Firebrand)
Jan 10 - Brawler Pack (Iron Fist, She-Hulk, Haggar, Spencer)
Jan 17 - Femme Fatale Pack (Storm, X-23, Morrigan, Chun Li)
Jan 17 - Villain Pack (MODOK, Super Skrull, C Viper, Wesker)
Jan 17 - New Age of Heroes Pack (Dr Doom, Sentinel, Strider, Akuma)
Jan 24 - Animal Pack (Wolverine, Rocket Raccoon, Amaterasu, Felicia)
Feb 07 - Weapon Expert Pack (Taskmaster, Hawkeye, Zero, Trish)
Feb 21 - Viewtiful Strange Pack (Dr Strange, Dormammu, Viewtiful Joe, Phoenix Wright, Tron)
Mar 06 - Value Pack (All 48 costumes for $20.00 / 1600 MSP)
I'd say it's worth waiting until March if you really must have all the costumes. Anyone going to be plunking down dollars on DLC suits like Arthur's below?

Capcom also notes that all content you've downloaded for Marvel vs. Capcom 3, including downloadable characters like Jill and Shuma Gorath, will transfer over to UMvC3 so you won't have to worry about double dipping. Who already picked the Ultimate game up?
