DrumCore 4, which is expected around mid February 2014. - so its still some way off
 
Looks like there is no upgrade path for Kitcore owners. The buy DC3 now and get the DC4 upgrade free offer puts Drumcore 4 at $199. I will be passing at that price. I wonder if they will ever upgrade Kitcore?

I asked about that in their forum but it hasn't been answered yet.  I have KitCore Deluxe.

Digging deeper on the website there is a path for Kitcore users.
 

DrumCore or KitCore User other than those above who wants DrumCore 4:
First upgrade to DrumCore 3 or DrumCore 3 Deluxe. For pricing, please contact support. Tell them what email address you used to register your current product, and what you would like to upgrade from and to. If you qualify, they will respond with DrumCore 3 Upgrade pricing. Register DrumCore 3. Then pre-order the DrumCore 4 Upgrade and get a free DrummerPack.

 Good find.  I asked in a support ticket also so I'l watch for the answer.

Cool! I was beginning to think Drum Core was done forever.

It looks to me that they aren't updating Kitcore at the same time - strange as I would have thought the two products are pretty similar - so perhaps they are just dropping the cheaper product, Kitcore and concentrating on Drumcore. It will be very interesting to see what price they want from us poor old Kitcore owners to upgrade to the full package - I know for me, unless very reasonable I shall not bother, and slowly slip Kitcore back into the draw of defunct software.........................

I wonder which we will see first Drumcore 4 or Sampletank 3
 
The current pricing of Kitcore Delux and Drumcore points to an upgrade price of around $100, more if you just have kitcore. So far there is too little detail to about whats new in Drumcore 4 to make a decision. I have little or no interest in the audio loops. It would take some new kits and MIDI loops to for me to justify that outlay.

Looks like Sonoma have taken a few leads from IK and their Custom Shop. From the KVR anouncment of Drumcore 4.
 

Online store for easily finding and purchasing content directly in the plugin.

Hopefully they don't go with the dreadful credit approach. Online shop I can deal with, credits not as much. Unlike IK though, they actually announced something, and are offering a decent incentive to pre order.
