I mean, I don't think anyone sets out to create a crummy product, so I'm pretty sure Wizards would like something that is perceived as better than what is there now.
But also like I've said - I don't think Wizards is interested in rocking the boat. I don't even think they're hoping to advance the game significantly mechanically with this release, but they can't pass up the anniversary without doing something special. IMO they'll call it a success if they release it and most of the complaints about it are "this isn't a new edition at all - it's the same 5e with different artwork and some tweaks." I think they'd count that as win not a loss.
