I should have been a little more clear in my initial reply. If the .yu TLD is going away, I think 2 years is sufficient. That said, I don't necessarily agree with getting rid of TLDs but I'm sure a lot of politics is involved when countries change names. Personally I've never really liked any of the localized TLDs precisely because this sort of thing happens. It has already happened a few times in the past - .cs, .dd (although it never made it to the official root nameservers), and .zr. The .su (Soviet Union) is, according to ICANN, being phased out but is still accepting new registrations.
