I'm glad things are unraveling, I really hope that the progress that's been made will result in his impeachment/indictment.
He'll never be impeached/indicted. He may be impeached if the Democrats take the House, but if they don't have the Senate, nothing will come of it. But the mainstream Democrats are political animals just like the Republicans. They won't impeach him because he's good for their business (fund raising, keeping the base energized, self-promotion), and having a wild card like 45 around allows them to grandstand and look good (see Republicans when Obama was president).
What they'll do is hold hearings, call people to testify, and milk this out for all that it's worth. Because if they were to actually successfully impeach and convict him in the Senate, there'll be a massive cathartic release once Pence takes over and a general feeling on the part of the public for it to all be over and move on.
The only scenario where I see 45 being impeached is if he wins re-election, the Dems are in control of the House and it's late in 45's term, so they can use it to their advantage in the 2024 election (see Republicans and Bill Clinton in the '90s).
