The number of expected new gTLDs is still speculative and will likely remain just that until the application period ends.  However there is a website of proposed new gTLDs that have been identified by Internet addresses and extensions. The site lists 106 proposed new gTLDs containing a mix of categories: community, ethnic, geographical (geo; country, region, city), IDN and specialized.  Not all known IDNs proposed are on the list, and .deloitte is missing from the brand category. The specialized category contains proposed gTLDs such as .car, .mls, .money, .music, .sport, .web as well as 26 others. 

A check of the supporting websites indicates a number of proposed gTLDs have backing and potentially viable business cases, while others appear to be seeking support and investment. There are likely as many if not more new gTLDs being considered that haven’t been announced, so while the exact number isn’t known it is apparent there is growing interest in the new gTLD concept.
