Pretty sure they said there won't be other editions this time and the season pass will unlock all characters but they can be unlocked free from playing the game itself.
From the top of my head reading bits and bobs so not 100%. But pretty sure the Tekken director said this was pretty stupid towards Ono in regards to this system.
Edit: Found sources
Season Pass includes 6 additional characters but can be unlocked playing the game - http://heavy.com/games/2015/12/stree...-order-capcom/
No multiple versions and on disc DLC - http://www.playstationlifestyle.net/...ions/#/slide/1
To be honest I was in that thought process as well thinking back to Street Fighter 4 but with the ever growing userbase for the PS4, meh I am not too sure. The CE doesn't appeal to me though so just want the steel =/
