Do you remember back in January, around the 20th I believe, when you where trying to get me into a prolonged back and forth as to the need for submitting the form since it wasn't listed on any official website?:
I told you to scroll back a couple of pages to see the discussion that had already taken place with regards to the DS form. It's obvious you never bothered to check and now you're panicking and asking me again if it's really necessary! I honestly can't help people who will not bother to do as told.
I scrolled back and checked the discussions but I haven`t found any successful cases without DS260 submission. That`s why I asked you again.
I found the post where @Britsimon said that visas will not be issued to those who don`t submit DS260:
"As cases come forward they are processed and not all will be issued visas:
- Some people will not submit their DS260..."
It seems he is pretty sure about DS260
