upgrading to Cross and DVS sync

2 questions really, ive been on the DVS mk2 (I think) set up for years now and was thinking of upgrading to Cross. Im not entirely sure what advantages Cross offers, i only spin DVS. Is it worth me doing?
And secondly do these newer DVS setups offer a sync? Ive noticed mixes and such on youtube with people using vinyl (DVS) but never touching the pitch. Tweeking the platter but not the pitch, last I knew sync wasnt possible with DVS.
