Browsing the internet sphere this Thursday, I stumbled on what is being claimed to be a legit leak on a MK2 version on the Pioneer DJM 900. The 900 first came out about 5 years ago, and has become a staple in the DJ booth. It came Traktor certified, then a Serato certified version came out. So yeah, it was Pioneer making sure their mixer would be the go to choice in the DJ booth.
If this leak is in fact legit, we might see a new mixer in the Pioneer line up for 2016. Just from looking at the pic, you see the form factor being about the same. the only noticeable difference is probably two USB ports, a min headphone jack, a new touchscreen on the right and some more control parameters for the effects section. With Rekorbox DJ releasing a DVS update soon, it would make sense to also bring out a new club standard mixer.
It is to be seen if there are more upgrades and updates, if this is a legit leak of course. Stay Tuned for the latest!
