Check out the product page on the Aerosoft website, you will see that they are going to be releasing a free upgrade in march 2011 in order to add the night textures to US Cities: Las Vegas.
Thanks for the heads up, I didn't know they were going to do a free upgrade.
Maybe then I will have a look at it. No point in buy it now though, for me anyway, and letting the installer sit on my backup drive until them. Frankly I would rather wait and see how it looks at night before buying, and of course make sure the upgrade gets done. I would hate to buy it and wait for an upgrade that for some reason got cancelled or they changed their mind on.
