As Cubby85 has said, everyones Destiny save data is stored on the Bungie servers. Provided you use the same account, and same console generation, your save will still be there.

Its worth noting that if you get an Xbox One, you'll have to go to Bungie.net and perform a transfer, otherwise you'll have to start over. (previously, the save was shared between console generations)
