Well, someone at Samsung is either in a lot of trouble right now for jumping the gun or the company doesn't care about its upcoming Fan Edition products, because Samsung Argentina has published a photo showing the Galaxy Buds FE, Galaxy S23 FE, and the Galaxy Tab S9 FE.
This photo comes from the Galaxy Buds FE page that went live on Samsung Argentina's website earlier today. The page mentions the Galaxy S23 FE and Galaxy Tab S9 FE by name, so yes, these products have essentially been made official at this point even if Samsung hasn't revealed all details (like the specs for the phone and tablet).
Of course, Samsung will still have a proper unveiling of these products in the near future. And that unveiling could take place on October 4, as that date can be seen on the Galaxy S23 FE in another image on the Galaxy Buds FE page.
Samsung has had a long tradition of sneaking in the launch date in marketing images of upcoming phones, and while the company hasn't been following that tradition too religiously in the last couple of years, an early October launch for these Fan Edition devices seems likely given how they have been popping up online so frequently over the last couple of weeks.
