I get your point but you’ve got it backwards imo. Detailed reviews come out whenever, especially if it’s a single guy doing all the work. Pre-release reviews are, at best, rushed (very few publishers will give review keys more than two weeks before release, and you usually have several releases to cover each week), and at worse, more or less dictated by the publisher (lest your publication get blacklisted and you never get a pre release key from that publisher ever again.
