Yes and no. During the Claims period, a registrant trying to register yourtrademark.tld will receive a notification that you own certain rights on this domain name. However, he can still choose to register the domain. If he does so, you will be notified about this domain registration.
In this situation there is no difference with the current TLDs: depending on the registry's policies, the existence of your trademark might or might not be a reason to obtain the domain name from the current registrant. Compare this with the situation that somebody registered yourtrademark.com – the same legal procedures should be followed.
