Any "list" leaks you see are to be ignored, especially the printed ones.
Game companies who are doing anything at E3 don't actually send lists out, because it's not required. The employees involved with setting up E3 are no wiser than us when it comes to what will be at E3, as they don't need to be told what they are setting up, they merely do their jobs. This is especially true with Nintendo who are not having a traditional conference, but are streaming various things on Tuesday and having developer-journalist round table Q&As.
The only leaks worth considering are single game leaks. For example, someone anonymously tipped that Kingdom Hearts 3 would be revealed at last year's E3, and it happened. Could have been a lucky guess, but in general, I'd get more excited for leaks that reveal single games if I were you. List leaks have a trend of listing obvious/confirmed things, conforming to fan wishes, as well as having one or two wildcards too, so they are not hard to construct.
