I don't see there being enough difference to warrant a clean T1 Police Shootout T-800. They'll likely just 2.0 the battle damaged version and possibly throw in a clean grey shirt instead. Just not enough difference in damage compared to what the T-800 had in T2.
Even the new clean T-800 2.0 from T2 won't accurately work for the Pescadero scene, He got bullet holes riddled through the back of his leather jacket in the mall early on.
If we do get a new T1 battle damage T-800 2.0, they won't give us a pleather jacket, it'll be genuine leather like the new T2 2.0's.
