Reply to DDJ-SX (Traktor) and RMX 1000 question

Hi guys, i have two questions.
1. Do you know are there any indications that Pioneer releases controller DDJ-TX (or whatever name will be), or is Native Instruments going to upgrade s4. I have s4 for almost two years it is great controller for that price but it lacks some things: booth output and control, real LEDs per channel, real manual gain (auto gain sucks), reverse button, better jogs. I believe traktor misses professional controller that would easily replace need for cdjs 2000, djm 900 mixers for users that use traktor professionally in big clubs and festivals.

2. Also I have question which is the easiest and best way to connect RMX-1000 to s4. One of the reasons why I would buy RMX-1000 is that traktor have some really good effects but a lot are not that good as pioneer ones. And I know one way to connect them and that way I would get RMX-1000 assigned all the time on master channel which is almost useless. So is there any way to connect them so you can assign it on separate channels?

Thanks in advance!
