New CDJ´s

Hey,

I am thinking of getting a new pioneer system. I have been looking at the DJM 900nxs2 and two CDJ 2000nxs2. 

Do you think its worth buying it now or waiting to see if there are any new releases  out at NAMM or the music convention in Frankfurt?

I would really like to see a new player like the DDJ 1000 with performance Pads and everything. 

cheers
