Although this is not an MMO trailer I feel like I still have to share it with you guys, as this is probably the best game trailer I have ever seen.

Cryptic has released the second part of the three-part CG trailer for Neverwinter, a new Free-to-Play Action MMORPG by Cryptic Studios, slated for release at the end of 2012.

Wargaming.net has released this spooky but interesting trailer for its upcoming MMO World of Battleships

At E3 EA Press Conference Ray Muzyka just announced new features coming this year to SWTOR:

• Free to Play to Level 15 (starting in July)
• New PvP warzone
• New Operation Called Terror From Beyond
• More Challenging Group and High-Level Content
• Nightmare Difficulty Mode
• Group Finder
• Ranked PvP
• Character Transfers
• New Level Caps For Every Class
• New playable race: Cathar
• A new planet, Makeb, will introduce new storylines and more.
• New space mission
• There are also new companion characters and playable species coming soon. new companions is an Assassin Droid!

Although we knew much of what was already announced the level cap increase, new planet, new playable species, warzone and operation were certainly welcomed news to the majority of players.
