I don't expect WotC will pay too much attention to 3rd party publishers when making decisions, at any rate.
What's really interesting to me with Odyssey of the Dragonlords (which is excellent - better than most first-party products I'd argue) is that WotC just hired the all three of the people behind it - James Ohlen, Drew Karpyshyn and Jesse Sky, into being in charge of their new Archetype Entertainment studio. So they're not exactly going to be mad with WotC!
They didn't exactly ignore it, I guess...
Confident Odyssey of Theros will be roundly inferior to it, but I have to admit, unlike the previous Magic book, I might well get Odyssey of Theros. I am a sucker for that kind of setting. Plus it sounds like it can be stolen from a lot, potentially, for other settings.
