The frequency of foreshadowing naturally decreases the further the game develops, seeing as Ren (and thus the player) uncovers more and more secrets. There will always be at least a few things, but never as much as in the first chapter.
Other things (like the one with Daishi you correctly pointed out) take a long time to get addressed, too, since they're either low-priority, extremely important, or dependent on a slow build-up.
The Daishi one, for example, is one of those that need the slow build-up. It's already been "addressed" a few times since when it was first mentioned, albeit not in a direct way. You'll see what I mean when everything gets unveiled eventually. :P
Thanks for your kind words, mate :)
