For all of these newfangled TLDs that are springing out of the woodwork with strictly for-profit interests, yes. Even some ccTLDs have seen rapid price hikes in recent years. I think the safest bet is to pre-renew the domains you really want to keep for as far out as you can (most registries allow you to renew a domain for up to 10 years). That way, if there is some major change to cost structures, you have a decade to either weather the storm or come up with a migration strategy.
