whatever you say bustr, AH still looks bad even compared to the older IL2 Sturmkovik series, so saying that WoP will look better than Aces High is a safe bet, even with Photoshopped screenshots.
AH2 engine is showing his age, also on the terrains topic, isn't it the custom textures that make the terrain files grow in size? I have trouble believing that more precise 3D coordinates would increase the terrain sizes beyond the acceptable.
HTC could start by reviewing/making more MA maps that use the refinements offered by the AH2 engine, not reprocessed boring and bad looking AH1 maps. It's been years and years we're waiting now.
Also in the years of broadband, 4.7Gb DVD's, 1Tb HDD's, the client download size is irrelevant. I'd download a 10Gb Aces high client with a big smile on my face.
