There seems to be a lot of confusion going on here. I'd like to add to that confusion by giving my theory of what is going on, based on the information I've gathered from this thread, mailing lists and things I hear from Nokians.

This is what I take as commonly believed fact:
1. "Dali", aka N9 was to be released late last year but was scrapped in the last minute for one reason or another. Dali runs Maemo 6 aka Harmattan. Some thousands of these were built before it was scrapped. Nokia wants to do something with these devices. Exactly what or how they will be used will most likely become clear the 21th. The term "Developer device" has been thrown around.

2. "Lankku" is a device that exists at least as a prototype, and claims have been made that this one will be produced for consumers. Lankku also runs Harmattan. Produced for consumers means much more of these will be produced than the Dali device. Apparently "Lankku" has faster hardware and no keyboard and is thin and beautiful. This device has not been leaked.

This is what I think will happen on the 21th:
Nokia will unveil Harmattan, Harmattan SDK will be released, a developer device program will be announced and information about when to expect the consumer device will be given. My guess is Q3-2011. But the device won't be in consumers hands before late November.

Regarding some other nonsense:
The number 92000 devices that people are talking about sounds somewhat plausible for the amount of Dali devices that were produced before it was scrapped. Obviously Nokia would not decide beforehand exactly how many devices would be produced. That depends on if they sell etc.


EDIT one more thing, I think that the Dali devices will be available for the developers very soon. They want development to happen before the consumer device is out.

EDIT2 The event is in Singapore not in Australia. Here's the schedule: http://www.nokiaconnection.net/event.php
