This one's easy. Last year, the Galaxy S24 started at $799. This year, the Galaxy S25 starts at...$799. It's a wash, in other words. That said, it's possible that Samsung drops the price of the S24 after the launch of the S25, but until that happens, these two phones cost the same amount of money.

The Galaxy S25 Ultra is one of the best Android flagship phones money can buy, but is it enough of an upgrade over the S23 Ultra?

What will be announced has not finally been decided yet. But certainly US, Korea will be announced (sic). And then that model might be available as a second (wave) launch.
