Seems like there is a ton of value in bringing guys up later in the season, if your team isn't a serious contender for anything more than wild card scraps. Wilyer, for example, started on his learning curve last summer, and needed a bit more time getting going, but was already half way up his learning curve. Of course he was billed as a more polished hitter compared to some top prospects like Ceddanne, whose education might last a bit longer and who needs his glove to justify the longer leash. Anyway, teams will need to be more strategic than maybe they used to be.
