I'm sorry but that all sounds like a bunch of contrived bullshyt.
The original movies NEVER alluded to anything of the sort. Vader was portrayed as a powerful jedi overcome by temptation, not some prophetic messiah figure here to bring peace to the universe.
Vader was on the dark side, the jedi were all but extinct.. they thought they failed ... there was no need to talk about a prophecy directly or indirectly.
but it was hinted when luke left dagaboh (whatever) and yoda was like he's our last hope and ben said there is another...
