Hint that GTA V is coming on PC?

In a recent Social Club update the following snippets were found referencing GTA V

X:\gta5\src\dev\rage\base\src\rline\rlsessionfinder.cpp
X:\gta5\src\dev\rage\base\src\net\task.cpp
X:\gta5\src\dev\rage\base\src\rline\socialclub\rlsocialclubtask.cpp
X:\gta5\src\dev\rage\base\src\rline\rlgamespy.cpp
X:\gta5\src\dev\rage\base\src\net\http.cpp
X:\gta5\src\dev\rage\base\src\rline\ros\rlroshttptask.cpp
X:\gta5\src\dev\rage\base\src\data\growbuffer.cpp
X:\gta5\src\dev\rage\base\src\system\simpleallocator.cpp
X:\gta5\src\dev\rage\suite\src\rgsc\rgsc\rgsc\profiles.cpp
X:\gta5\src\dev\rage\suite\src\rgsc\rgsc\rgsc\presence.cpp
X:\gta5\src\dev\rage\suite\src\rgsc\rgsc\Release\socialclub.pdb  

Rockstar Games would not add those files for no particular reason, right?
Also, Rockstar always releases the PC version 5-6 months after the console versions.
There's always a hope!
