I'm actually fairly interested in the WiredTiger integration. I switched from MongoDB to TokuMX about a year ago because of disk space and atomicity concerns, and Toku's been really good to me. Mongo 3.0 promises to catch up in many respects; if it does, then it might actually solve the vast majority of the complaints that people have historically had with it. The marketing copy still pretends that TokuMX doesn't exist, though - it's had these features and more (including transactions) for quite some time now.
