Apple Watch

God help me but I am thinking of getting an Apple Watch and I could use some advice. My first instinct is to blog buy the current watch and be happy. But now I hear the /Series 8 is coming out. Is this a huge jump typically? I can’t really find any info on the 8. When they come out are they typically difficult to get?
Apple is having an event on Wed Sept 7 so if you have not purchased one yet you may want to check it out. The jump each year on the Apple Watch is usually not that significant though.
