The TLA space is pretty limited.

It's not like anyone is going to run out of disk/memory space having 
"PlayStation4" strings in it. :-)

My general stylistic opinion is that global names should be a bit verbose, and 
local names should be short. (Yes, you can find counterexamples in the code I've 
written.) Instead of having a naming convention grammar for globals vs locals, I 
find the length to be quite effective.
