EN serves only 3-5 years for manslaughter, that is if he doesn't get off completely by an acquittal.
I currently think those are the most likely outcomes. Just going off KM and BM's description of events it is clear there is no pre-meditation where the shooting didn't start until the Meyers themselves say they chased the Audi. Here's some interesting reading:

The sketch could really come back and bite the police/DA as that seems to be the basis for the premeditation as you'll note this article is from 2/19 the day of the Criminal Complaint: "
Metro said Thursday that Nowsch was the man drawn in a sketch police circulated to find the shooter. That man was described as being in his mid-20s, 6 feet tall and about 180 pounds with spiked dirty blond hair and blue or hazel eyes."

However the Complaint gives some critical details that the driver who made the alleged threat is not the shooter where according to BM and KM: "The daughter said
a white male approximately 6' tall got out of the driver's seat of the silver car and said 'I'm going to come back for you and your daughter'...Brandon said his mother stopped the car and the
front passenger of the silver car began shooting at them...Brandon said the car was approximately half way down the cul-de-sac when the
front passenger leaned partially out of the passenger window and began firing west toward his mother and his mother's car."
Insisting that growth hormone taking EN was the one in the sketch seems detrimental to the police/DA when it will be easy to argue EN never made the threat and by the Meyers own account, the Audi didn't fire upon them until after Meyers chased the Audi. It's not to say that EN can't or shouldn't go to prison, but the DA/police shouldn't keep on perpetuating silly easily dismissed arguments that will undermine them in front of a jury. This seems like a crime of passion where EN reacted in the heat of the moment after being chased (he felt threatened too, but it is universally agreed upon he was chased). EN may have been present in the car for the threat if this was one long back and forth where that scenario could both help and hurt the prosecution, but if the police/DA keep going around in circles on what happened and insist EN was the driver mistaken to be 6' tall that itself creates reasonable doubt for the jury.
EN's indirect description of events can be read as either two events or one long event. If it is one long event that presents a challenge as it means the Meyers were out driving armed from the start and it also calls into question which of the Meyers were in the car. All three of them could have been in the car or KM could have ran inside while TM ran outside and got caught in the crossfire or some other such scenario. If the Meyers were out driving armed from the start that could explain why there has been so many lies and it really calls into question what was going on, which the truth could be that TM was just a bystander who had nothing to do with this and ran outside after her kids flashed the pistol and were involved in a chase and shooting. No explanation sits quite right with me though, but the Meyers proactively being armed and looking for trouble would be a strong motive to lie as KM and BM would not want to say that. Even if TM was driving that still means BM was riding around armed in the passenger seat before any threats had been made, so BM in particular has a strong motive to cast more and more blame on TM as time has gone on.
