SNW v4.1.2: Coming Soon™

G1-Neume revealed some news about the next Sword of the New World update in Next Major Update Details forum topic.

It will include all updates from the Korean version from 3.5 to 4.1.2. It will NOT include Sorceress Emilia (that name may change) as we've previously announced. I also want to point out that we have received the next major update and are working to put it on our Montoro Test Server as we speak. We intend to release this to a limited closed beta in the near future.1

The few tit-bits he revealed so far are mostly features of v3.5, so I will link them to existing feature articles in sGE below. Costumes are linked to the respective screenshots.

• Summon Friend Scroll available in Feso Shop for 10k feso each. See Scroll of Destiny.
  
• Jewels can be upgraded. See Eeny Meeny Miny Moe!.
• Reduction of maximum Upgrade Accelerators needed. See sGE v3.5 Patch Notes.
• Alejandro can wear metal armors. See sGE v3.5 Patch Notes.
• New premium dungeon - Sacred Caebolan. See Sacred Chaos Requiem.
• Skill points can be reset. See Skill Restoration.
• New colony war system. See New Colony War.
  
• New necklaces available n Errac. See Craft Your Own Necklace.
• New costumes include Torosmata Ren (m/sco), Slendor Reaco (m/wiz), Clarcana (sco), Shaggy Bobcut (f/sco), etc.
  
• New back costumes include Crystal Wings (temporary, ATK +10%, ATK Speed +10%, HP Absorb 5%, Undead/Golem ATK +15%).
• Premium and gold packs will be removed from SotNW Marketplace to be replaced by 3 new gold packages. Target/GMG Cards are unaffected.

Portmanteau VI
In addition, Portmanteau VI boxes will include Sith.² I will assume this means Sith will be replacing Panpan.
