It all depends on what "THE" cuber means

Nakajima, being the WC, will be the most well known outside of the cubing community because of the media, and that he handled the pressure well.
Matayas and Erik mastered so many puzzles, being like the Jack-of-all Trades, which require lots of dedication and efforts. Both have done amazing records...I don't know who to choose haha.
Gungz (Yu Jeong Min) set the 3x3 Avg record with a HUGE margin at the time, from previous 13.22 to 11.76, which a year later no one else has even sub 12 yet (but soon). But may be THE cuber in our minds is somebody that came out more recently, in the last half of the year?
anyway, let's see who's going to be THE cuber of 2008 ;-)

P.S. Erik was right to decide not to put my name on there, because I haven't been able to perform as well in official competition in 2007, and I'm only good at 3x3, nothing else much (though I'm working on it haha). There's still a long way to go.
