Edit: Also, its interesting how our thirst for knowledge has changed to a level of entitlement expecting to know 100% about a product prior to its release. Years ago reviews didnt actually come out at all until retail availability was possible and some dude bought the product on the shelf and did the review.
(for the record I'm not saying anything for/against this, just observing how times change.)
Entitlement? Companies provide review samples in advance of the release date and control when the flow of information is released. This isn't entitlement, this is the way product releases have evolved.
