That would be a big claim, and not totally correct because we don't necessarily see ImpressCMS and wordpress as direct competitors. That would also imply that we would make the same choices Wordpress has made and that isn't so in many cases.
Granted, I would be thrilled to have ImpressCMS power a fraction of the number of sites Wordpress is running on at the moment, but given our very different target audiences I don't think that will happen overnight
ImpressCMS 2.0 is described as a technical milestone : no more old legacy support, new architecture. I feel that the version of ImpressCMS that comes after that should be a functional milestone : new of improved functionalities on a number of things. It would be great to see what points you would like to see improved, so that we can start a discussion for that before starting to implement it.
