There's no way it can be perked when it's new. There would be a riot, if people in cyber-space could riot.
If the Ki-84 turns out to be uber, then it will get perked. Historically the Hayate / Frank could outclimb a P-51 and out-turn a Spitfire, so "uberness" will depend on what top speed HTC gives it, I suppose.
For the record, I think the D-Pony, 190-D, and La-7 should all cost a few perks, along with some others, like the 109G-10.
