Just to be awkward, I want different things from different products.
At this point in time, I want the Core Rules to be consumable - I already know what RPGs are, I don't need to know what a dwarf is, and I'm not looking to be drawn into the hobby. Just tell me what I need to know to play the game! And the same should apply to most splatbooks, books of magic items, and so on.
But the Starter Set absolutely should be designed to engage with new players - they need to be drawn in, they need to see the action in their mind's eye. Roleplaying games can be quite hard to grok; the Starter Set needs to help them with that!
Likewise, setting materials and adventures should be designed to engage with the customer, whether said customer is experienced or not.
As for "cherish"... I'm not sure they should be designing products for that purpose, at least not in the core line. The reason the author cherishes his OD&D booklet is not because of anything inherent in the book - it's the memories that he has associated with it. The same is true for me with my Red Box, 2nd Ed core books, and 3.5e PHB - the reason I prize these so highly is because of endless hours of memories of gathering with good friends. So that probably shouldn't be a major design consideration.
(That said, there's certainly an argument for doing a "collector's edition", or leather-bound version, or whatever for the new edition. That's fine... but they should probably make the game a success first, and then give it the deluxe treatment.)
IMO, of course.
