Here is my favorite part:

"the developers were able to make everything up to 16 times more detailed this time around. You'll once again be able to fly anywhere in the world, landing at any of the over 24,000 airports on the seven continents. Using an advanced GPS technology, there are authentic road layouts, and you'll actually be able to fly over your hometown and navigate by the streets below. Flight Simulator X will feature approximately 24 real-life aircraft, including an Ultralite for those gamers who don't want to deal with dozens of dials and knobs. "

Some things I already knew from looking at screenies and watching videos but also very cool:

"Flocks of birds flew through the air, dolphins frolicked in the surf, and cars drove down the roads we cruised over."

"the team designed a number of missions, including point-to-point objectives and skill-based flying (barrel rolls, anyone?). Of course, you can still leisurely fly around the world if you'd prefer that to ferrying passengers or cargo around. "
