N-Gage is there as a platform rather than a phone model series. So if you get a new S60 phone next year you could have "N-Gage" by default. So they're demoing next-gen stuff http://pandora.luxus.fi/e3blog/e3_06/video/ca8f384610fe4875b70266c2120b9e49.swf.aspx alongside new games that run on the current N-Gage phones

as well as white pvc

N-Gage goes on, though Nokia is moving from N-Gage, the modified smartphones that they insisted on selling like traditional game decks, toward, N-Gage, the online gaming platform for smartphones.

So you won't be finding a future "N-Gage" in a GameStop, rather Nokia Nseries and future S60 smartphones will download the new games off the network for multiplayer local or worldwide (Arena) play.
