what's going to happpen next in the midle East between Iran and Saudi Arabia

After studying this more carefully my conclusion is that unless Russia or the Houthis set this off like a bomb with more missiles into Saudi Arabia or into Iran this will once again resemble more the cold war between the Soviet Union and the U.S. from 1945 until around 1990 when the Soviet Union financially collapsed.

This is a cultural and economic war mostly in the end anyway between two dominant Oil powers, one being Shia (Iran) and one being Sunni (Wahabi) (Saudi Arabia) mostly. So, what is more important religion or oil economics for both countries?

In the end bringing war directly into either country would likely be  disaster for both countries just like the Iran Iraq War in the 1980s was ONLY a disaster for Iran and Iraq and nothing else.

However, it is possible that the next proxy Iran-Saudi Arabia war could take place in Lebanon the way this looks right now. But, it's too early to tell for sure at this point.

I think Europe and the U.S. and what they want for Lebanon is likely what will happen in the end. What Israel wants for Lebanon will be important too because Israel just like the U.S., England, France and a few others has nuclear weapons too.
