not a fan. way to busy and it looks way to bulbous and bulging all over. interior is nice but the entire car looks like someone took one of those squishy toys that eyes bulge out of it when you squeeze it.
car looks like someone squeezed it and the lights, bumpers, fenders, are all exploding out of it.
Our current gen F's are much more aesthetically pleasing IMO.

I hope it looks better in real life.

The redline is at 7400 rpm (about 600 rpm higher than the IS-F) so the rev cut off would be around 7800 rpm. The engine is very different from the one in the IS-F.

The car has badass looking sporty body except for the front end. If they can close the wide spreading open mouth at the bottom and use the current IS F grill on the upper part then this car would look more classy. See how the BMW, MB & Audi fronts look w/o too much awkward funky design. All these new F sport spindle grill with wide spreading open mouth can't last for long.
The Motor Trend article says, the engine internals have been reworked for more power at the top rpms and internals lightened to make it a proper high-revving engine with a top rpm heavy torque curve (as yaguchi san put it eloquently, "we developed the torque curve to be like mount Fuji).

Yaguchi san said that they purposely decided against a flat torque curve in favor of a steeply surging torque curve to give the driver a sense of never ending acceleration. I believe it will feel similar to IS-F till around 5000 - 5500 rpm and then go crazy over 6000 rpm screaming all the way to 7400 - 7750 rpm. The torque curve shape vision is said to be "using mount Fuji ascent for inspiration".

Of course, everyone really wants to know what’s under the hood. You’ll find the same cast-aluminum block that’s now doing business in the IS-F, but everything else about this DOHC 5.0-liter V-8 engine has been revised. Lightweight titanium valves are again matched with strong, forged connecting rods, but there are new cylinder heads that still incorporate variable valve timing on both the intake and exhaust cams. The polished crankshaft is smaller in diameter to reduce friction, while the pistons reduce friction as well. Naturally the intake manifold and exhaust headers are new, and the exhaust barks with a sharper, louder note. The dynamometer numbers aren’t yet final, but we’re told that this engine spins faster than before to deliver at least 450 hp and 384 lb-ft of torque.

More details about the engine in the link below. Was surprised to hear the words Atkinson Cycle mixed in there! Apparently the compression ratio will be variable. Cool stuff!
"A switch to electric phasing on all four cams brings greater variability and precision, and lets the engine borrow the Prius' more efficient Atkinson cycle operation during low-demand cruising conditions."
"The ideal Atkinson cycle captures and compresses an amount of air that, when combusted and expanded throughout the entire power cycle, results in a cylinder pressure that's near atmospheric at the bottom of the piston's stroke, meaning the engine has wrung every bit of energy out of the fuel. Drop the hammer, and those valves shut in time to give you the full 12.3:1 compression (up from 11.8:1) and 5.0 liters of furious power — 480 horses' worth (up substantially from the IS F's 416)."

Like all new cars, it will simultaneously attract some all new buyers and turn off some of us former "F" fans. I predict that after the RC-F is seen out and about on the streets and showroom floors, many of the current ISF owners will come around a bit.
I personally like (not love, but like) it, and it is currently the front-runner to replace my current ISF, though I won't be lining up to get one and I will probably wait until at least the 2nd year of production before seriously considering the change. The ISF is still a special car, no matter if this RCF ends up with 480hp and is appreciably faster. Plus, I'm partial to the 4-doors.
And of course, the price is still the big mystery.

Ahhhhhhh... I got a major epiphany this morning..... I really want to upgrade to the RC-F but I can't spend $70K on a car right now. Guess I'll wait a few years til the used versions come out and depreciate.
