New P101 Launcher Backgrounds! Class-Themed Houses?

Seems like if you login to P101 now, you'll see some class-themed backgrounds on the launcher.
You can see some I got together in the following picture:

What could this be hinting torwards? In W101, recently there were some Aquila characters in the launcher background and days later, Aquila was announced, could this mean class-themed houses? Class-themed housing items? New bases? New schools?
Guess we'll have to wait to find out...
