Almost no registry has announced prices yet, as they have no final 'go' to start the registration services. In general, we can say that prices will vary a lot: there will be low-priced TLDs ($5-$10 per year), medium-priced TLDs ($30-$60 per year) and high-priced TLDs ($100+ per year).
On our website we will publish a list of TLDs and their relevant information, and update it when more information is available.
Please be aware that most registries will also have a group of domains that will be marked as 'Premium', resulting in an increased price for these specific names. If the domain you want is premium, it will be mentioned during the ordering process to make sure you are aware of the higher cost.
