I'm wondering how they keep it a secret. Seems like there would be leaks or "spies" that would provide clues prior to official releases.
In anycase, to me it's a clean slate - they could go in any direction. I'm looking forward to the new larger color screens, expanding the possibilities of SPIKE, continuing the creativity. Not all the pins are hits.
I have no guesses but I'm still interested in knowing before anyone else.
