The initial release software completely depends on the production date. I just purchased a brand new Phone (2) on Amazon Germany not even two weeks ago, the device was produced in December 2023 and I got an immediate update notification to 2.5.5 and after updating it also found the latest 2.5.6 right away.
If it’s worth or not depends on you own preferences. I just like the Phone (2) so much that I purchased it again after selling it earlier this year. Four years of security updates should be mid 2027, sure we’ll most likely be stuck with Android 16 by then, but at least for me that’s not too much of a big deal - especially since I can imagine to maybe upgrade to the Phone (3).
Of course if you are planning to keep the phone for four to six years, there are better options for long term software support out there.
