The Japanese Phantasy Star Universe site has listed details on what to  expect for October 10.

Hidden update
Minor spawn changes to White Beast.
A key location has been changed.

PM GH 490

This new Partner Machinery is loosely based after Moomins. It carries it’s own rappy backpack and wields very interesting weapons. You will be able to obtain PM GH490 at “The Collector” by Parn Leaf Cafe . Remember those Megashi Arms, Legs, Torso, and head, we’ve told you to collect? Well this is the reason why you’ll need it. But wait there’s more! if your looking to wear Howzer’s disco outfit in the future. I suggest holding on to this EX Device.

Please Note: Your PM’s Battle Stat or B.Stat must be 100. You can raise your battle stat by bringing your PM to missions with you. You can raise it faster by S ranking C level missions.

Neudaiz Move Pass

Now you’ll be able to transfer your room to Neudaiz using the Neudaiz: Transfer remodeling ticket. Players can enter their rooms through the Neudaiz Guardians building. However you’ll need to bring a few items to “The Collector” before you can obtain it.

• Scroll
  Collect these items inside boxes scattered across Mizuraki Conservation Disctrict
• Paper Latern
  Buy 20 “Neu Wood” and “Neudaiz Souvenir” at MA-GRMS Neudaiz
• Kakwane Figure
  Buy Kakwane Figure at MA-GRMS Cylez and synthesize with 3 Kakwane Tails and 10 Gra-Photon
  Suggest buying Kakwane Tails or hunt at White Beast but the majority of you should have them already.

New Collector Exchanges

Some brand new creative decoration items should be available, including the music discs that feature songs from Neudaiz. Most of these item exchanges require specific drops from specific enemies.

Expected Downtime

All Phantasy Star Universe servers will be down at an unannounced time in the future for ISP maintenance. The date has been moved from October 11th.
