I see the g37 becoming something like the GTO. Great power, but with that power comes a lot of weight to carry around.

As far as gearing, its more aggresive than the current G35 & 350Z; Final drive for both auto and mt is 3.7, while the G/Z have a 3.3 for auto & 3.5 for mt.

My brother has an '06 997S which we've taken to the dragstrip a few times. We were never able to match the low 12 sec 1/4s listed in magazines like Road & Track and Car & Driver. I then read where Car & Driver launched the 997 at 5K RPM to get their best time. I was launching at 3K RPM and getting 12.6 - 12.7. That's why I don't believe that 1/4 mile times listed in the magazines are all that important since not too many people are willing to abuse their cars to get their absolute best times, and 5/60 times are a far more revealing measure of a car's capability on the street.
If you look at the 0/60 and 5/60 times of cars with a lot of torque like the 400 lb/ft C6, you'll find that they are nearly identical. On the other hand you'll find that the 5/60 times are slower on cars with moderate torque outputs because they require that high RPM launch.

Let me put it this way: when the VQ37HR is put in the z, it will smoke the 350z, and even the g37.
And you keep concentrating on ET's. ET's are a measurement of traction and gearing, not power. Even if the coupe and the z had the same engine and weighed exactly the same, the z will out-ET the coupe. The g's wheelbase is 8 inches longer than the z, so the z has the launching advantage(read traction).

.. am just gonna be dissapointed if the g hits 13.7 or more ..

Sigh... same rated hp/tq, but comparing dyno charts the G37 dyno's 23whp more. The e46 M3 is more in line with the VQ35HR output. Therefore same hp:weight ratio.

What you aren't calculating is gearing, traction, HOW MUCH ACTUAL TORQUE instead of where you peak torque is. Where you're maximum torque rating is has little to do with what rpm you should launch at.

I would love to see low-13's but in reality my 04 was fast enough for me and that ran in the 14's, so whatever this is will be good enough as a DD.

Assuming traction is no issue, I'm pretty sure all cars would run a faster time at higher rpms (higher horsepower).
I like looking at 5-60 times as well. I think they are a good gauge of what you experience on the street. High powered AWD cars sometimes have very low ET's but crappy 5-60 times. Obviously, the car runs what the car runs - but for street performance I'd rather have a car with a high flat torque curve than a one with a similar curve to an s2000.
That being said, I think the G37 (similar to the HR sedan) will have the best of both worlds. Good low end torque (relative) while also spinning to 7500 rpm.

The G's power delivery is constantly building to redline. This will make it's power much better for racing applications. Typically cars that have awesome midrange punch feel much faster than cars that build power to redline.
