The absolutely biggest problem I have with the old logos is I can never find a high resolution image.
Whatever I do get produced, if enough people pledge, will be released in high resolution, with psd sources.
Hmm, this sounds like a no-brainer to me. It is fairly easy to vectorize those logos, or it should be achievable at least with some (professional) skill/effort.
To me, additional logo seems more and more like waste of good resources... But you can vote with your wallet.
