I think it is GR5.  If it were a new version, they would have put out an image with some new components.  It looks like Fast Compressor, Soldano, Control Room Pro, Stereo Detune.

Thanks for setting me straight there guys.
 
If they actually include even a reasonable version of the new symphony stuff it will be tempting. I have KU 9 and I think you can upgrade from one or two versions back for relatively not a lot especially if they do an upgrade sale.

Yep, not bad, but I'm good with K10U until the summer of 2017 when upgrades are half off.

Those one knobs are definitely the NI symphonic libraries in one form or another. My guess is they are scaled back versions of the full releases, but I'm just speculating. I'm on K9U still, so this update may be worth it this time around, but I won't decide until the official announcement. I see Una Corda in there, so that's quite tempting. Also, if Kontakt 6 is released, that would almost definitely seal the deal for me. 

I dont have Komplete, and are feeling like the odd person out!
Should I succumb to peer group pressure, is it worth it! or should I resist the tempation?
If next version has woodwind and reaktor 6, I may even have need of it!
I am betting on a realease for 11 next month, after seeing indictions of price rises on NI products next month while shopping for a midi keyboard.
My head hurts, its all too much, think I will go get a chai latte!

If they actually have decent orchestral stuff, It seems like a great package. Of course that might just be in Ultimate. In the old daze it was excellent for synths, drums / percussion, bass, effects, electric keyboards and pop strings / brass. Of course Kontakt and Reaktor let you into whole worlds of 3rd party instruments. The pianos, guitars and orchestral stuff were weak. From what I understand the new pianos in K10 are very nice, the new acoustic guitar seems good. If they have added quality classical strings / brass / woodwinds then I don't see many real weaknesses in the package. I think one weakness would be a good electric guitar anyone else think of any?

Maybe a new full blown synth 
And upgrade that old guitar thing, as well as of Kontakt, of course.

Looks like they've got "One Knob" series going on in there...

bet they all go to "eleven"

The only things in there I don't recognize from Ultimate 10, apart from the "one knob" things, are some Indian percussion, an Una Corda piano, Tim Exile's "Flesh" (for drums) and an acoustic guitar. Oh and Reaktor 6 I guess.

11 must be on the way soon. They have had the others on sale for a couple months now haven't they? I'm thinking Una Chorda at Christmas half off for $49.00 then sell it next summer in time for 11U upgrade half off.
