@eiffel, I understand knowing the answers to all your questions will make your short term life as developer easier. But if we haven't disclosed them by now is because Nokia thinks that by following certain marketing strategy the devices with Maemo 5 will have a better impact and will sell better. Which ultimately is a goal shared by most developers interested in the Maemo platform: most of you want more users for your software.

Then again, can you name the projects you have in mind for Maemo 5 and why all these questions are critical? If you can't really start seriously before having those questions answered fair enough: do not waste your time. All these pre-releases are made for those willing to get started before a product launch.

Before that product launch you can try the SDK pre-releases or you can ignore them. The worst combination is not to ignore them and not to have fun with them, spending your energies in especulative threads like this and writing the especulative post number 225.
