Just as a point of reference, this building will be taller than both of the fallen WTC buildings stacked on top each another (sans the spire).

Yeah, the Burj is itself mind bogglingly tall, this new one is only 10m taller.

I'm wondering when we're gonna see the first true Mile High tower? We're 1/3 the way there!

We're actually over 1/2 way there.

1 mile = 1609.344 metres Burj Khalifa = 828 metres

If it's only 10 cm taller, that sounds like within the margin of error of where you measure. Not that I have any idea what the standard "building height" measurement entails.

IT will be 10meters taller, not 10 centimeters.

oops

We can measure the distance to the moon accurately enough to determine it is getting 3.8 cm furhter from the earth each year, I'm pretty sure 10cm is well outside the margin of error for measurements of something as simple as a building.

Once you know what to measure, that is true. However, in 'tallest of the world' attempts, there typically is quite a bit of uncertainty about where spires (included in height measurement) end and antennae (not part of the building) begin (http://en.wikipedia.org/wiki/List_of_tallest_buildings_and_s...).

Not disagreeing with you, but I wonder how much the Burj expands and contracts every day.

Certainly much less than 10 meters
