no major changes is my bet.
2006 Apex
2007 Phazer
2008 Nytro
three newly designed sleds in three years.
My bet is small improvements. Maybe all the non-mountain sleds will be EFI
RX1 was produced for three years
Vector was produced for three years
Now the Apex is on its third year.
I am expecting to see a new big power sled.
