ISC2 Training material

in (ISC)²
I completed my CISSP training last April, have taken a break and now focusing on CCSP. Im mainly relying on Sybex again and the CCSK PDF.
I was also looking at CAP and IISMP but I have to say the official material is years old and the reviews online are disappointing to say the least.
Why aren't ISC2 releasing upto date materials? It seems we need to refer to NIST an awful lot, which is fine, but there is a danger of spending an awful amount of time reviewing subjects we don't need too etc.
Any thoughts?
