Well I am just sitting pretty with my 18.5 gallon tank.
But seriously, I can see the smaller tank size being an issue for track days. I got close to running mine out after a long day of lapping at about 10mpg. You know how V8s get when you get on em.I imagine it could go a lot lower if I was actually getting up to speed.

My GT4 resale value just went up.

Problem is, they didn't SWAP prices, they FLIPPED position on prices.
So the Boxster used to be cheaper than the Cayman. They bumped up the Cayman's price above the Boxster. And now they've bumped the Boxster's price over the Cayman's current level. They should have priced the Cayman at the old Boxster level and priced the Boxster at the old Cayman level (swapped prices, not leapfrogged prices).
They just shafted people again...
I love the idea of the traditional flat six engine but it's hard to argue with the specs and performance of the turbo 4s. I'll never buy one new but I always prefer the general simplicity and reliability of normally aspirated engines.
I can't see a 100kg weight increase (at all) - 220 lbs when you're lopping off two cylinders but adding turbos and the required plumbing? No way!

I can see a weight reduction in the future. When the next generation platform is developed and designed around this forced induction powerplant I'd imagine that both weight reduction and adjustment of vehicle weight distribution could occur. In current form however, I'm under the impression the platform was optimized for the flat 6 engine. Next generation better be a smaller car as well. Wheelbase and overall size creep needs to stop

I thought most inducted cars turbo or supercharged are generally about 200 lb heavier than their NA counterparts?

70-100 lbs would be typical if you keep the engine's physical size the same (ie, go from a 3.0L N/A to a 3.0L turbo). However, they've cut 2 cylinders off, so that would represent some weight savings.
I'd be surprised if it was more than 70 lbs, personally...

As much as I love the sound and overall character of the 9A1 3.8L in my GT4, it is definitely a little flat feeling down low. I may be spoiled though with the garage mate having over 600lb/ft of torque (basically double the torque at lower rpm), but it would be nice to have a little more low-end punch on the 3.8L. FI fixes all of those "problems"
That said, I'll still take the NA 3.8L anyday over a turbo 4 for my fun car, but I totally understand why Porsche is doing it (power, emissions, fuel economy, etc.).

I'd say that ZR1 is definitely highlighting the "lack" of torque in the GT4. Most of us probably wouldn't notice. 
The new Cayman S is 0.2s faster than the GT4 to 60mph, according to Porsche, but that's with PDK vs the 6MT in the GT4. I'd bet the Cayman S with MT will probably will be neck and neck with a GT4 in a straight line.

Porsche is always extremely conservative with performance numbers - take them with a grain of salt. Boxster/Cayman S with PDK has been a sub 4.5 second to 60 car for going on 6 years at this point.
The new FI engines are considerably torque-ier. I wouldn't be surprised if some of the weight gain is from heavier duty drivetrain components designed for the higher torque level.
