Just as a note of warning, this game is listing on that mini-site as being a DirectX 10 game, which means Windows Vista ONLY. Those of you on anything older won't be able to play, assuming they stick with the DX10 (and being Microsoft, I bet they will). The line coverage map on their page looks rather densly packed, though, so assuming it's even close to what they plan on doing they may have coverage for most of the North American lines (Guilford/Pan Am anyone? )
With respect to the new MSTS site (http://www.tsinsider.com/en-US/Pages/default.aspx), the screen shots look amazing. You definitely can tell they're using the Flight Sim X engine and the latest in 3D modeling.
And though the shots are small, see also: http://www.tsinsider.com/en-US/product/ ... fault.aspx
I'll likely be replacing my Dell in the next year or so. I guess I now have an excuse to load up the video card side of the new one.
