Seen this from ICM?
We have also applied for three new gTLDs with ICANN; .Sex, .Porn, and .Adult. If we are awarded any of these extensions, we will automatically reserve your matching .XXX domain names in these new extensions for you at no additional cost. You, and only you, will have rights to the names. Within the next year we hope to secure these new gTLDs so that we can protect your brands in those new TLDs or alternatively, so that we can provide you with even more market reach if you choose to use those TLDs to promote your websites. To find out more about our gTLD applications and unique ?grandfathering? program for existing .XXX domain holders, check out the information at
