You have to upgrade the core game. Period. What we have is better than Aces High I with 250 vehicles/planes.
You bring up FSO/Scenarios. Part of that experience is feeling like you're 'there'. Good graphics improve this 100000x. I can't wait to fly FSO this month. This will improve the experience for most players, especially going from the freaking patchwork quilt terrain we had before.
On the subject of maps, those are player made, always have been. We have like 3 maps that were made by HTC. The new TE isn't out yet; it may make things much easier... meaning new maps.
There's a lot more to this update than you seem to think...
