Any Date for Wave 9 Previews?

Since I expect to see the mid-way point of wave 8 releases later this week, I was curious if there has been any thought on when we might see the previews for wave 9 (and possibly some hint as to the theme for wave 10)?

There’s been plenty of hints on wave 10 over the past few months. Some say parts of it are going to be out of this world.

Last of the photography is coming in now, so we will be doing a wave 9 reveal stream soon enough I am sure.

Its a doozy.
