I wouldn't bet on this: - The lifecycle on the market for a smartphone has shrunk to 9 to 12 months for the last two years. The Xperia 10 was introduced by Sony in early spring 2019. - A typical sign of devices being EOLed is that Amazon themselves stops selling them (i.e. only "Amazon marketplace" sellers remain): This is already the case for the Xperia 10 and 10 Plus.
