Truth be told, at this point unless their Max plugin has a far superior UI I don't see why I'd switch over..
Over the last two years I haven't used Max at all, and I've gotten so accustomed to Blender that I'm much more productive with it that with Max. (not that I ever was very fluent with Max anyway..

) Sure Max has a large number of superior features, but for most things Blender works very well. (ok its UV mapping feature set is horribly painful)
Also, for the newcomer Blender is less intimidating that Max, and we already have a good deal of documentation going on here to make people feel right at home.
I dont' think the proportion of people using Max vs Blender will be that high, especially in the beginning.
