I don't think so. Based on what they wrote in their application for the 'app' tdl, Google, in the name of Charleston Road Registry, plans to totally close the TDLs they get :
Charleston Road Registry intends to operate the proposed gTLD as a closed registry with Google as the sole registrar and registrant. The goal of the proposed gTLD is to allow Google and its Network to manage the domain name space for their application offerings. The proposed gTLD will provide Google and its Network with the ability to customize domain and website name application offerings to signal to the general population of Internet users that .app websites are indeed managed by Google. The specialization goal of the proposed gTLD is to extend the Google brand and reputation to each .app second-level domain. This specialization provides a mechanism by which Google and its Network can easily link and manage their applications and related services. This specialization makes it clear to Internet users that this is the authoritative and designated space where they can find Google’s and its Network’s applications offered in association with the Google brand and accessible via differentiated and streamlined web addresses.
