As you may have heard already (or read on my blog here), Adobe announced new Creative Cloud applications, including the new Photoshop CC.
Adobe will keep selling Photoshop CS6 and customers using Photoshop CS6 will keep getting Camera Raw 8 updates.
When Adobe updates Camera Raw 8, Photoshop CS6 users will be able to get the updates and work with updated Camera Raw 8.
However, no new features or functionality will be available in Camera Raw to Photoshop CS6 customers as part of those updates.
There is no official information from Adobe on how long Camera Raw will be supported with Photoshop CS6, and not just for Creative Cloud members.
