Pokemon's not dead "yet' it has a pretty good chance of dying after this 5th Gen, considering the atrocious and downright idiotic Pokemon Designs as well as the vomit-inducing english names...
The only reason Pokemon lasted into this year with the mainstream is all because of Heart Gold and Soul Silver, that brought back a lot of the old school gamers who fell in love with G?S but gave up on Pokemon afterwards.
If it wasn't for HGSS, Pokemon would have easily been dead by now....
BTW when i say dead, i mean Dead n the US, cause i know it will never go away in Japan...but Pokemon has been close to going extinct as far as US sales are concerned
