For WOTC on others its probably a good marketing decision. For one you have limited marketing spaces on shelves, limited advertising budget, etc. While the old expression, don't put all of your eggs in one basket, is a good one, it might not apply in such an environment.
The efficiency of selling one megabook as opposed to many smaller books is a big bonus, think of all the money they save on cover art alone. And of course there's the wow factor as was mentioned. You can't help but think these books are better than anything you've seen before, there's just so much crammed in.
