I'm trying to decide whether or not the Ki-84 will be perked. It seems like the P-51D and the La-7 are the 'ceiling' for performance. Anything that matches and/or beats them in certain areas seems to be perked. Not even overall utility, in my opinion, or the Ta-152, Spit XIV, and F4U-4 wouldn't be perked.
Be interesting to see if the Ki-84 is introduced as a perk plane.
Indeed, Urchin!
I remember the exact same sort of discussion that started when Tac first posted his "UFO"

pics of the Spit14.
Generally, there is a basic "Golden Rule" of WWII fighter evolution that "maneuverability and speed is incompatible".
If a plane turns good, its slow. If a plane is fast, it turns bad. There are acceptable limitations on each aircraft which, by pure (and extremely lucky!) coincidence, very favorably balances a game depicting WWII combat. Since those two factors are usually incompatible in many planes, it tends to draw attention of pilots of different preferences.
However, like the Yak-9U, La-7, Spit14 and so on, there are rare cases of planes that the two traits are not incompatible, and it is these planes that usually bring out the "to perk, or not to perk" balance problems.
I guess we'll have to see if the Ki-84 becomes the new "N1K2" or "La-7" in the MA, but if I read the specs right - the Ki-84, which is mentioned to out-turn a Spit9, would be the fastest of the so-called "turner" category we've ever seen so far. It's top speed may not be anything special(at least not as fast as in US tests with US fuel, which recorded woppin' 427mph), but somehow I imagine it to be something like a La-5FN that turns like a Spit9, or N1K2 that is as fast as a La-5FN... and just thinking about a plane like that makes my skin crawl out of fear
Boy, and to think fighting P-38Ls in an E-disadvantage in a 109 is tough! In those situations, when in a 109, P-38s feel like fast Spitfires when they stick to your tail... Ki-84 is going to bring on a lot of pain!

....
If the Ki-84 is perked, so should the others be - Yak-9U, La-7, P-51D, Bf109G-10, Fw190D-9, N1K2-J... around 3~8 points. If these planes stay unperked, I guess there isn't any real basis behind perking the Ki-84.
ps) Bring on the Ki-84!!
With this baby, PTO setups in CT is gonna be really interesting
