Andrew Meggs has posted a message at MWA saying that the recent MacSoft announcement rules out a hybrid disc for Myth III. He also informs us of a new editing tool that was developed for Myth III:

Editing Myth 3 will involve a new thing we call Vengeance, which is in no way a reference to any dealings any Myth 3 team members may have had with a former Chicago-based company. Vengeance is built with a modified version of a cross-platform library called YAAF (see www.yaaf.org), which allows us to sit in CodeWarrior and with a single click generate functionally equivalent versions for both Mac and Windows from the same source code.

Meggs also notes which machine they'll use to demo Myth III at E3 next week: 1.2 GHz Athlon with a 266 MHz frontside bus on a Gigabyte motherboard loaded with 256 MB of CAS 2 PC2100 DDR memory, a SoundBlaster Live! Value, and a GeForce 3. Mac users don't fret, as he didn't omit the fact that the Mac version of Myth 3 looks identical in every way except for the case of the computer that's running it.
