Guys I found this article quite interesting (quote from dchiuch):
"Nintendo registers all [pokemon name].com names, even prior to the Pokemon being officially announced. If you look at the whois information for yveltal.com, fennekin.com, etc, then you can see that they were all registered on December 21 (well ahead of the announcement) with Melbourne IT.
These whois services usually offer a reverse IP lookup tool, which I believe would show all other domains registered by the company. domaintools.com shows "44,447 other sites hosted on this server.", which if you buy a report, you can see the list. From there (I think), it would simply be a case of looking which domains were registered on December 21, and we might get the rest of the Pokemon names?
I'm not sure if there are any free alternatives for reverse IP lookups. Everywhere I look seems to take a fee. Any ideas? It's not worth any of us regular folk to pay $x00 to (possibly) find out some Pokemon names, but perhaps fansite owners would see it as a worthwhile investment to break a big story?
Just wanted to put this idea out there"
I checked on that site and almost all of the leaked names were available for buying..It could be that they have not registered them yet, but yes not so cheering.
