I was also very excited when I heard this, in fact I can't remember anything else that came out of E3 after hearing about the remake.
The PS4/Vita exclusivity doesn't bother me, it will come to PC eventually. I'd rather have Grim exclusive to PS4 for a while than it being left buried in Disney's basement
In fact, I believe that it was probably only by using the leverage of Sony that Tim Schafer and DF managed to convince them to licence Grim at all.
Now I eagerly await the release date and the merchandise (where the real money is made)
