There isn't anything insinuating the "update" will come in the form of a Press Release (could be various outlets); "throughout the week" has a different definition to many. For me it encompasses Sunday through Saturday.
I don't like the PRs identifying dates or insinuating additional content/information being distributed within specific days/dates; nonetheless, it is Friday after all 8-). It's been communicated to APT; avoid these types of indications moving forward, if at all possible.
