I think we will find that most of the memo is just a synopsis of the 99 pages mentioned in the video and posted here.
This is the 99 page report on the FBI and FISA court. from 2016

I expect you're right -- except...
The 99-page FISC report had all of the scoundrels' names redacted.
IMO, The Nunes FISA Abuse Memo will be a synopsis -- with accusations -- and with all of the known scoundrels' names printed for all to read.
IOW, the people of America will then know who should be hanged... '-)
