Everything that is listed at 
http://newgtlds.icann.org/en/program-status/delegated-strings

Or almost everything that is listed at http://publicsuffix.org/list/effective_tld_names.dat and is not a 2-letter TLD. 

I think it's a safe guess that if TLD is unknown to the code, it could try whois.nic.<TLD>. It will address most cases yet to come. 

But if the idea is keeping up to date, http://mm.icann.org/pipermail/gtldnotification/ mailing list provides every contract signing for a TLD that ICANN makes. After subscribing, parsing of received alerts can be automated.
