What happens after Maemo 5?

The last post was insanely popular and I thank you all. The InternetTabletTalk thread is FAR more interesting than the actual announcement. Here's something that has come from discussion so far:

The developers are going to have to release software compatible with the new abilities of the platform. It's up to Nokia to provide an SDK where developers can write one code base and export it to go to all tablets.

The new CPU, HSPA radio, and camera will add cost. There will be users who want to pay less for a device without the HSPA radio. Will they have that option? Is the market big enough to support two tablets?

How will carriers interact with this new device?

Head to the forums to talk about these in depth. Expect me to pin down some of the developers and community members here for interviews.
