I am not sure if you guys got the HUD sorted out, but I hope you don't make the mistakes that were made with the 2097 HUD.
Anyway, I had an idea for the weapon icons (forgive me if this is in the wrong thread). With the Quake, for example, it could combine the icon from WipEout HD with the one from wip3out, where it starts as a lowercase Q, and it then straightens out into two parallel lines, then it spikes and finally straightens out again with two arrows at the end. Pretty cool, right?
As for the Turbo I think it should use the same icon as it does in HD, but rotated 45 degrees and it would start with a thin arrow, then a slighty wider one, and then a much wider one.
TL;DR It would combine the WipEout HD icon with the Pure icon.

Sorry in advance, but I haven't been on these forums very long. This is in fact my first post.
