Well I'm not lying, Runescape 3 was announced that there would be one on the news page that it would be released sometime around, i cant remember the exact year, but i would be somewhere around 16-17 when it was released, and my friend who played with me told me I was a loser if i still played when i was that old. Sorry m8 but i was incarcerated when I was 17-18. Wikipedia is not always accurate.
Not sure if you played back then, but you would have read it on the news page, Rs3 was literally just a dream, it wasn't even something people talked about, they just mentioned that there would be one. I'm not posting to argue with anyone, Sorry if you didn't see it back then mate, and I'm not sure if there is an archive. Just simply trying to give a bit of background of myself and my Runescape experiences.
