As pointed out by Droid-Life, Google's next midrange phone, the Pixel 6a, has popped up at the FCC.

What's most surprising about the listing is the timing. The Pixel 6a's April FCC arrival is the earliest we've seen for the A series in a long time. The Pixel 5a was listed at the FCC in July 2021 and launched a month later in August, while the Pixel 4a hit the FCC in June 2020 and also released in August. The first Pixel A phone, the Pixel 3a, had a February FCC listing and launched at Google I/O in May. This year, Google's (virtual) I/O event is May 11, 2022, so that day is currently the odds-on favorite release date for the phone.
