>>11687925For previews of upcoming/unreleased stuff:
https://youtube.com/@YTeamHotwheels/videosI already know people are going to be put off by the speaker's accent, but this is the only channel I know of that consistently shows previews of upcoming releases from diecast brands (MiniGT, Greenlight, Tarmac Works) besides HW/Matchbox. The problem is, you'd have no idea going off the thumbnails alone because usually only HW/Matchbox are ever shown on them. The HW/Matchbox are featured for the first half of the vids while the other brands are featured in the latter half. This channel is where I got this screenshot of this pink Fuji Models 370z, releasing February.
https://youtube.com/@Diecast24com/videosThis channel is just pans across the new catalogs for brands like Maisto, Welly, Bburago, but it's useful for quickly going through and seeing if there's a model you want so that you can research it later.
For unboxed/detailed reviews of new stuff:
https://youtube.com/@levelmdiecast2329/videosMostly Matchbox, but reviews other new stuff like Majorettes and some Greenlights and occasional 1:18 Maistos.
https://youtube.com/@Championdjk/videosHas some reviews of new Majorettes, Autoworld, MiniGT, Johnny Lightning, Greenlight and other lesser-known diecast brands.
https://youtube.com/@Spent2MuchDiecast/videosMostly HW, but does some pretty detailed reviews of 1:24, 1:32 Jada cars.
https://youtube.com/@eiraku/videoshttps://youtube.com/@omotyannerun/videosThese are Japanese channels that show Tomica brand cars in detail. Unfortunately, @eiraku is not immune to the reach of Hot Wheels.
