XLN will still honor the Solo and Producer bundles that come with SONAR Professional and Platinum. 

What does that mean? If we have AD2 through Sonar, we can buy AD2 components (kits, pieces and beats) without "upgrading" anything else? I hope so. I didn't see any kind of announcement on their site, although I guess I wouldn't be eager to make one myself...

Interesting Post ...I purchased AD 2 sometime back ...well before Platinum 
had some slight problems getting the ADpaks deal ...XLN customer service was prompt in their replies to help solve my problem. That's about it ... since purchasing Platinum, I've had to purchase the midi paks ... no problems with that process

Wish I could help with others' difficulties...

Here's my take on that Larry (from experience)...
 
Yes - no further upgrades required.
 
If you got AD2 with Sonar X3 Producer you got the ADpaks/MIDIpaks/Kitpiece as defined in post #2.
 
If you upgraded to:
Sonar Platinum - you get an additional 3 x ADPaks, 3 x MIDIPaks, 3 x Kitpieces, of your choosing.
Sonar Professional -  you get an additional 1 x ADPak, 1 x MIDIPak, 1 x Kitpiece, of your choosing.
(Using the same AD2 Engine, and typically maintained through the XLN Online Installer (occasional patch updates which is notified from within the installer)).
 
You are free to purchase any additional XLN Paks/Pieces independent of Cakewalk. But it appears that XLN are no longer offering the Bundle Paks (independently).

Having looked at their site it just seems like theyve changed their product packaging.

They are still honouring the Sonar bundle, other than that everything is still the same. If you want to upgrade all your AD1 packs to use with AD2 you pay the upgrade price. It's been that way ever since AD2 was released I think.

I mean if you got AD1 with Sonar and AD2 with Sonar they're only asking you to upgrade your AD1 packs for a price.

If you want 3 more kits, midi packs and kit pieces, buy another copy of SONAR Platinum. You will have a year (from now) membership and the best prices on the Addictive Drums stuff. I may have talked myself into this.

OR....
You can look for a good deal at KVR..........I actually bought a couple of bundles and got more thrown in than what the Producer Bundles offered........for much less.  
 
Of note, there's a guy selling his Sonar Platinum account over there.

You can actually only get one copy of Platinum at the discounted/upgrade price. And buying a completely new license isn't a very good deal if all you want is the ADPacks.

FWIW I actually don't mind this system, I think they caused a lot of confusion by NOT having this system, especially for those of us who had AD1 and then got the AD2 bundle, what with the upgrade of old content being separate from the AD2 engine. It makes sense to me that you buy a drum program with some basic bread 'n' butter kits and then you can expand on it.

Thanks, Shellstax. That's what I'm hoping and expecting. For many reasons, I'm delighted that I went for X3 and then Platinum, but in the beginning it was Addictive Drums that sold me, because I was already looking for a 3rd party app that was better than Session Drummer. So if XLN was going to start getting hinky, I'd be unhappy, and maybe un-Addicted.
