Windows 8 RTM after the release of the retail version

hello everyone, i have a Windows 8 pro x86 RTM and i wondered, when the retail version is release which is the same thing, does the RTM version get all of the updates as the retail ones?

Also can i use the RTM version as like the retail version?

P.s i have fully activated my windows 8 (permenant activation) acording to typing slmgr -dli or -dlv or -xpr at command promt(admin).
