Any ideas of sequels for JK Rowling?

If I were doing it, I'd write a sequel set maybe around the early 2030s: The wizards at this point are coming realize that muggle technology is approaching the capabilities of their magic, so they decide to reveal themselves and integrate the two societies in order to avoid getting left behind. Naturally, this plan doesn't go over very well with a lot of people on both sides, launching a struggle between those who want peace and cooperation, those who want total segregation, and those who want to annihilate the other side because 'it's the only way to be sure'. At the same time, those on the cutting edge start combining magic with science and technology, producing far more advanced theories and devices that threaten to leave the purists on both sides in the dust and bring about a sudden, drastic paradigm shift in human history.
