Any development on the mighty RB is always well and truly welcomed IMO. You do have to get to a point where you say enough is enough however.... Particularly for us non Sydney based "normal" GT-R owners that don't want or need 1000hp.
It may be an unfair opinion but I really feel that the Japanese (tuners/worshops/performance part manufacturers) have become irrelevant in many ways. The vast majority of the "big name" tuners and workshops are just basic workshops using basic tools and basic principals. There are obviously some that are absolute artisans at what they do and for some, the work they do is what they're after. The Japanese have become famous for NOT innovating. Take cars and motorbikes for example. Honda, Nissan, Mitsubishi to name a few sell very outdated, very basic vehicles. They're running "new" tech that Euro brands were using 5-10 years ago.... All of the motorbike brands we knew and loved as kids are now so outdated they're almost not relevant in todays offroad market (Honda, Suzuki, Kawasaki are the main culprits). When I was 12 or 13 I would have given anything to own a KX80 or CR80 two stroke dirt bike. They were just so iconic back then. Now there's no chance I'm riding anything other than a KTM, Husky, etc as they're chalk and cheese in terms of tech, bike weight, ergonomics, etc. I bought a brand new Suzuki for my son a few years back and it was so bad (heavy, drum brakes, etc) that I sold it and bought him a 2 years older KTM 2 stroke that is 10 years more advanced than that bucket of a Suzuki.
Greddy to name one previously massively respected and somewhat innovative brand has to a large part realised they're no longer relevant and are leaning on Aussie companies (PRP, Artec, etc) to supply "their" new tech. Maybe HKS are still big enough and relevant enough to actually pull off some significant RND and then produce some up to date components to bring to market? As previously stated however they're living in the past when they were still relevant when they work out their pricing. It's ludicrous what they charge for their "Fine Spec Engines". I'd go to CRD/Powertune/Dahtone/ETC and spend half the money for twice the outcome any day of the week. HKS are only relevant to American Youtubers who haven't caught on yet (yes you TommYFYeah you flop) that Japanese stuff is (unfortunately) not what is used to be. Who knows, maybe this will be the first big step in the right direction and inspires other Japanese performance shops to break the mould and move with the times! The yanks will no doubt really ramp things up over the next few years too. Through shear weight of numbers they will come to the party with development of new RB platform add ons. Copies of Aussie stuff to start with then they'll no doubt find their own lane and add their own spin on things.
Either way it's awesome that so many businesses across the world are still developing a dirty stinken lump of steel block from back in 1985!
