This is a good question.
What Marc and I have discussed at this point is a corrected printing, available at a reduced price to everyone who bought T5 original.
BEFORE that, I have heavily suggested some serious reviews, and the way Marc is handling Personal Combat is a test of "Don's Proposal".
Basically, my proposal is to take the core chapters that are required to run a game (ie, not the 'makers), find the most dedicated critics, have them review the existing errata for completeness (that's what I've send out already to two of the five nominees for combat), then I'll sit with Marc and he'll bang out all the fixes and review it for coherence, then Rob/Don/"the secret cabal" will review it, then the five nominees for that topic will review it, and then I hope to leak it onto COTI for public critique.
:nonono::CoW:
So for Personal Combat (which I consider the #1 priority on the list of topics), I've asked for the five nominees, got them, contacted them, had two responses, and sent them the existing RED errata (aka, the Marc only material) for them to check for wording, completeness, common sense, etc. Then I'll review it with Marc, and he'll bang out his fixes, the secret cabal will review, then the nominees, and then I'll ask for permission to leak it here.
Other than the leak it on COTI part, Marc's agreed to that for Personal Combat, as a test.
Also, Marc is doing much better, for anyone who has deduced that he was going through some medical procedures...
