Man most of the pioneer products cost $2k and more - you know that - that "cdj form factor toraiz" will be no difference I am afraid and obviously one of the reasons why the link integration is being held back :-(
With the link integration, most of the people would be simply using laptops and controllers like a launchpad or apc but by not implementing the standardized midi or link, the users are not given any choice than choosing a product which is part of the walled garden so it sells better and any competition is silenced - thats the reason for calling it "gimmick".
I might be wrong but then the right question is why I am feeling like this and if company's communication with its customer base is correct and why such a small effort is being invested in such a highly demanded feature.
