Reply to New Traktor Controller soon? Please?

OK, this may be a redundant question and Traktor seems better than even Apple at keeping secrets (of course Apple has a million or two more followers) but I'm an Itch DJ looking to make the dive into Traktor. I like what I've seen and used so far in Traktor and I am fighting the temptation to buy the Kontrol S4 because seeing that it's now about 2-1/2 years new on the market and Traktor decided not to put out a new controller with Pioneer, I am assuming that there must be something new in the works.

Soooo... that being said, I don't want to shell out close to $800.00 for the S4 and then, SURPRISE!, something newer and totally more "awesomer" comes out the next month.

Therefore... does anyone have an idea, clue or inside info as to if and when a new NI Traktor controller will be released and replace the S4 as their flagship baby?

Thanks!
