More than likely a marketing decision. If I were them I would give the N810 a two week head start before releasing the OS to an established (and vocal) user base such as ours.

This will allow the initial reviews to be done using the 810. New hardware, new users, new OS = more enthusiastic posts.

Much better than... "I can't believe they didn't correct bug XYZ" or worse; the armchair, Monday morning quarterback comments about who they should market what to when...

It also gives developers another month to provide OS2008 apps and hopefully will forgo the "It doesn't run my XYZ app, I'm going to roll back" posts.

Also hopefully, enough members who qualified/won the discount will post so that N800 users will be able to decide when the best time to upgrade is VS. jumping in as soon as it's available.
