That info's in the section linked-to, the answer is:

"That said, please do not take this yet as a commitment to fully productise MeeGo on N900. I am quite confident that we will end up having a really good developer distro for N900 already but committing to stabilise a consumer-grade MeeGo 1.0 (first half this year) for N900 is another story. That is a product business decision beyond my scope. Also, we do not yet know about MeeGo 1 release content. I am not yet sure if I would be personally ready to let my Maemo5 go for the first MeeGo release in my daily N900 use."

In other words, the chance of a consumer-ready flavour of meego on the n900 (at least anytime soon) is slim, what's coming are semi-functioning developer-use-only installs. Whether a consumer release comes soon or atall depends on managery executivy types, not developers.
