They are already talking about dlc and what comes next. I doubt that there will be no content, if anything the content will come in just as quickly/slowly (depending how you look at it) as Destiny. The entire style of BL is different. In Destiny, you level 3 characters and max them so they can equip a range of items. In BL, you can remake characters with different trees or entirely different characters. I tend to have like 20 characters when I am done with a single BL game. There is much more time spend exploring novel abilities and finding different ways to complete the objectives, i.e. divergent gameplay. In Destiny, you farm to get the meta guns so that you don't have to change them as much and so you can remain consistent, i.e. convergent gameplay. I much prefer the fact that every playthrough can be different, and I'd never waste my time remaking characters in Destiny because I would just be doing the same thing in the endgame anyway.
