It's not on the roadmap for N900 and they are focusing on getting it done for the next generation of Maemo devices instead. This means, without a doubt in MY mind, that we'll never see this for the N900.

If they are talking about getting Maemo 6 done in a year or so and they won't even look into making Ovi Navigation available for the N900 before it's up and running for next gen, then we'll never see it. We'll all have Maemo 6 devices long before we can realistically expect it for the N900.

I really hope I'm wrong.
