It's only temporary and after reading some of his Google+ posts it seems like it might become a regular thing if it goes well.
For Jurina she has been sick and she goes to school in Tokyo and AKB is then closer instead of her always having to go to Nagoya. For Milky Aki-P thinks she can learn from Yukirin and Mayu.

"I believe that this is going to benefit SKE and NMB.
If this decision proves to be a failure, I am willing to resign my position as the producer of SKE and NMB.

Even if I have to risk my job, AKB group has to move forward."

AKB will disband after Tokyo Dome Or a member will graduate
Team 8 members will be announced because they said they were working on Team 8 Team 8 members may be members of SDN, or what if it's another team shuffle?
or something positive
A US tour?
We will see.
