Both praetors and Thrun die from state-based effects.

SBEs resolve after the second praetor resolves. SBEs see that Thrun is at 0 toughness, and is thus placed directly into the graveyard. Regeneration cannot replace the 0 toughness event; it only deals with lethal damage. The Praetors are both placed in the graveyard as per the legendary rule

A few things State Based Effects aren't a thing they're state based actions, second SBAs don't resolve, they can't resolve because they're never on the stack they just happen, third regeneration replaces destruction events not just lethal damage, and four the legend rule is a state based action.

Fifthly, none of this disputes the interpretation, so you should probably save pedantry and nitpickery for interpretations that are wrong.

Truth, but I'm a nit picker I pick nits. And based on my experience just because someone explaining something understands what they're talking about if they explain it in a poor manner or with the wrong words things get misinterpreted. Like saying SBAs resolve implies they go on the stack.

It's like getting uptight because someone called it 'in play' rather than 'on the battle-field.' Or someone said 'Removed from the game' rather than exiled. 'State-based effects' have been 'resolving' according to the rules as recently as 2011. So, being nitpicky about something that's only changed within the past couple months AND YET WORKS EXACTLY THE SAME is a waste of typing space. Again: Spend it on people who are wrong, not people who are using terminology that was correct last year but has changed.

After going back over the rule book, it does seem that the 'Everyone dies' answer is right. I was on the verge of being outraged that the legend rule would actually still let you make use of the abilities (albeit briefly) and then remembered that just how few such Legends there are with static -x/-x effects and calmed down a bit.

I was also fairly sure that the Legend rule worked such that they are never both actually in play at the same time, but it seems that I am wrong. Again, so few Legends around with that kind of ability (and honestly this kind of play is a bad play anyway) that its just never come up. I have played a Kokousho to kill my Kokusho post-combat for a ridiculous life swing, but thats as close as its ever gotten.

Always nice to be asked questions that make you learn the rules better. I bet if you tried this play at a tournament you'd have to get a judge to make most opponents believe that you kill their dudes as well as both of yours.
