My own preference would be for more formats. However, that has to be balanced against negative reviews by people who expect a cheaply-made original to somehow experience a massive jump in quality due to ordering a "premium reprint."
For example, the story of the Ouya console system. To sum up, Ouya inc. announced a $100 console system that could fit in your hand, stow away easily pretty much anywhere, and let you play mobile games on your TV. To kick the project off, they turned to kickstarter, and, as of the last time I checked, they still hold the record as the seventh-highest grossing project.
The project, needless to say, funded; units were produced and shipped; Youtube reviews went up...And "two-thirds" of them (approx.) by my rough, anecdotal viewing count, were complaining that their $100 console was, in fact, literally a $100 console. The other "one-third" simply noted that their $100 console was, in fact, a $100 console, and exactly what they were expecting. Sales sunk, and many purchasers sold their units on EBay.
Sadly, the company failed, and was bought out, because they delivered exactly what they advertised...And not what many purchasers seemed to expect.
Note: I was not involved. I did not, and do not, actually have a use for a $100 console. I am just noting that only one-half of what you say matters; the other half is what they hear. And the third half is what third-party listeners overhear.
To sum up, which POD formats are made available is a matter for the marketing department, not common sense.
