They've announced it, but at the same time I could drive up to my local Walmart right now and buy one. (That said, there's your Transformer Tuesday)
Looks like they cropped out all the white a bit too much: Hasbro really couldn't care less for this poor guy
Sideswipe is great! Already got him, Jolt and Grindor to join the rest of the RoTF SS cast. Just waiting for The Fallen, Sideways and the twins. Has someone found out anything besides a posible 2022 first quarter launch for The Fallen? Prototype images, box scans...? I've been a little behind news regarding them due to work and didn't find much around the web, other than some fan made images of what they could possibly look like.
Anything that has more tangible evidence than "leaker talk" is collected in this thread: Newly released and upcoming toys: Hasbro edition
