According to Raspberry Pi CEO, Eben Upton, in an interview with YouTuber Jeff Geerling, the company put together 750,000 Raspberry Pi units in the first quarter of the year. That isn't a lot, but it also says that it's on track for building 2 million units this second quarter, helping it fill backlogged orders and paving the way for "unconstrained" supply during the remaining half of the year. Ultimately though, it means that you should expect units such as the Raspberry Pi 4 to be more widely available by the end of this year.

Tom's Hardware reported in September 2022 [tomshardware.com] that the RPi foundation had revised their USB-C power socket to work correctly with the e-marked cables it was having trouble with before. At that time they intended to finish selling their stock of the previous revision, resulting in a temporarily-mixed supply stream of "maybe/maybe not" products.
8 months and several million shipped units (none of which made it to hobbyists) later, I'm confident that the next time I'm able to buy a RPi 4 at MicroCenter it will be one of the new models.
If not, the forum demonstrated a DIY fix, [raspberrypi.com] which is a solution provided that you're brave enough to try it.
