Just thought people should see this article. Some new gTLD prices are going up 3,000%.

ICANN has no price caps on how much a new domain registry can raise prices. I assume this will be an issue raised at future meetings.
For now, they can raise domain prices as much as they want when they want. They can also do registry clawbacks and mark you domain as a premium after the fact.
I’ll stick to .com/.net/.org and ccTLDs.
