The problem with repurposing ccTLDs is that unless the domain string/extension is something with a mass market appeal, it is going to be extremely difficult to monetise or develop. The registry is going to make money from all the true believers and fans but the second part is the most important. A lot of repurposed ccTLDs are not developed to the same extent as .COM or a local ccTLD.
There's going to be a lot of marketing rubbish about development levels in the new gTLDs (remember .CO ccTLD?) floating about and I would consider some of those trying to measure development levels to be complete spoofers. (One good indicator is when they say they are only sampling a limited number of domains rather than the whole TLD.) It is a very difficult thing to do properly and accurately and the registries often use consultancies who claim to measure usage but can't tell a simple redirect from a Godaddy PPC parking page for undeveloped domains. Generally you've got to check every domain/website in a TLD and properly analyse the HTML and the usage category and the context (is it really a website using that TLD or a website from another TLD where the owner just pointed it as the primary .com website without a proper 301/302 redirect etc). It also requires the holding page signatures/REGEXPs for thousands of different hosters. Then there are the clone websites which are the same website under many different domain names.
The usage patterns for new gTLDs, especially in the first year will be low because apart from cookiecutter template sites, it is expensive to develop websites and the mom and pop businesses (the real drivers of development in domains) will stick with the .COM and .ccTLD domains. What the professionals will be looking for is a trend best explained as the Abandonment Rate. This is where a website is set up (often using Wordpress or Joomla) and the registrant gets as far as the "hello world" post and then gives up (or if it happens later in the lifetime of the domain, the development stops with no further updates on the site). Normally you need a few years of survey data to do it but a lot of early market registrations do end up like this and do so in the first few months of operation.
There will be a few quick flips of keyword domains for seemingly high prices in new gTLDs. Some domainers may even get lucky but a lot of domainers are going to repeat the same mistakes of .EU, .MOBI, .ASIA, .TEL, and .CO. Apart from some carefully targeted ngTLDs, most of them are actually not really globally or regionally attractive TLDs.
