Pretty much. This kind of decision will only be made more and more in the following years. It's no shock DVD's are being phased out for both Digital sales and BD, surprised it's taken this long. Just the cycle of life, gotta adapt sooner or later. The extended cut could also be out to purchase on itunes and vudu weeks before the actual disc release like other titles.
At least theres the option to still play DVD's in all BD players. It's a much easier transition then VHS vs DVD imo, and has fairly cheap pricing for players.
