Maybe calling it a "news" letter is a stretch, but Blair posted the Tool Newsletter for January over on the official site. You can skip reading this one if you're not a fan of Blair's style. All it seems to discuss are some centipedes showing up in people's Vicarious DVD cases, and some kind of strange 'vision'. If anyone has a codex or Rosetta Stone to translate from Blair to English, I'd be happy to hear from you.
Other than the newsletter, there doesn't seem to be much going on in the Tool world. Maynard is keeping busy with the first live Puscifer shows (all 3 of them) and wine signings for his Merkin Vineyards, and there's a picture of Danny at the NBA All-Star game at the official site.
