Yay for open-source.
A Mr John-Paul Gignac has provided some new pieces to be used in glChess (and other such projects). So probably in version 0.9.3 there will be two sets available (with the high-res new versions as default).
Unfortunately I haven't had enough time to make a proper release. The SVN version has been tinkered with (re-enabled texturing - hopefully someone will provide better textures/colours HINT HINT). But it isn't clean enough for a release. I have no plans at the moment for easter so maybe some good work then...
