Wheelbase : 2730 (2IS) 2800 (3IS) 2850 (4GS)

Included for interest the Infiniti Q50 dimensions :
Length : 4783
Width : 1824
Height : 1443
Wheelbase : 2850
BMW 335i dimensions:

Length: 4635
With: 1811
Height: 1430
Wheelbase: 2809

So it looks like the 3IS is slightly more than an inch longer, has a slightly shorter wheelbase than the 335i, but practically identical width and height. Unladen curb weight on the 335i sedan is 3,545 lbs.

This means the 3IS should have around 3650 as the curb weight. It may not be any faster than the current iterations even with the 8 speed.
last night i found info about weight - it is extra 20kg, 45lbs basically. I forgot now where i found it, but it was a quote from head engineer about performance that ended up as explanation on how they tried everything to reduce weight of new model.

it was "20kg motor for motor" basically. So it should be less than 3600 for 350.

the 4GS even with all the changes weighed 50 lbs less. Assuming that 45 lbs extra is true, makes sense since the car grew a couple inches

yes, but as you say, 3GS did not grow in size.

Latest Motortrend article is showing 3,700 lbs for curb weight. I hope it is wrong.

meh 50 lbs gained is a good trade off for 3 inches of extra legroom.

Furuyama-san claims his team “tried to reduce the weight as much as possible [with new IS], but engine to engine comparison, the new one is about 20kg heavier than the old one”.
here is the quote, found it.

Two sources confirm about 50 lbs. Thats awesome. I bet the 1/4 acceleration will be a bit better as the 8 speed should negate any penalty for weight at 50 lbs. Better rear seat room with no speed penalty = WIN!

I'm liking this car a lot now.

weight gain was to be expected with the car growing 3 inches over the 2IS. With the gain only being 45-50 lbs its obviously they applied weight reduction like they did for the 4GS which lost 50 lbs.
