I'll give you the same answer I give every DJ who asks...
Pioneer is ALWAYS working on "the next thing," regardless of what it is.
If you are a working DJ and need to buy new gear, buy it. If you can wait, you'll probably continue to wait forever because when the next gear is released, you know they're already working on "the next thing," and will start doubting whether you should buy the new gear or wait for the next gear.
Pioneer doesn't have a timeline for releases, but announcements are typically made around the time of major international trade shows. We also never release any information in advance, so don't hold your breath.
Buy what you need, when you need it.
