or are they still 4G?
i think they should still be 4G because the major changes that they made were on the inside, and a generation change usually means a new physical change.
ie:
1g>2g
added a cover to the firewire plug
used touch wheel instead of scroll wheel
2g>3g
used dock connector instead of plug
changed button positions and became all heat sensored
3g>4g
changed button positions again, and moved back towards mechanical.
changed the menu and in the second reincarnation of 4g, used colour screen.
