There is no doubt that esports is big business and domain names with esport, esports and with and without a hyphen have all sold already (I even sold one! ).
The .xyz extension has an active thread currently with contrasting views about whether it is a good investment or not. It is true that in the last two years there have been a rather small number of NameBio sales, and most not at that high a price. However, if you look at the Report Completed Domain Sales thread there are a significant number of sales of xyz the last few months. Not all of them are at Undeveloped, but the majority are, and I would urge you to list your name there.
In terms of price, I think something low to maybe low-mid $$$ is right. Best of luck with it.
