Well, we know a big redesign is in store for Google Play (see here, here, here, and here), but today's 5.10.29 update doesn't actually include that. Technically, it might be that these big design changes are controlled on the server side and simply waiting to be activated for end users, but we just don't know yet. Update: Confirmed, see updates below. Regardless, today's update is probably at the least laying the groundwork for the new version, and does include one noticeable visual alteration: the new Google Play text logo.
