It's because timezones. It's already Saturday in Taiwan.
Apple was waiting for a production implementation of the spec which was published in December. The ball has been in their court since then.
Both materials feel cool to the touch when initially held. I'd say the titanium is a bit more grippier which might be relevant if you like to use your phone without a case.
The colours are matched more on the back and frame for the S24/+ compared to the S24U.
In general, the bootloader of US and Canadian models can't be unlocked. You can with other regional variants, regardless of Snapdragon or Exynos.
Notably mentions 5 OS updates for Google, which may end up being the policy for the Pixel 8 series (so far we only know in general 7 years of updates).
Noticed a few things here:
-They're still advertising UPC Plus which means there probably hasn't been any changes from the Fold4. Software processing for the camera might be different though.
-They're not advertising Eco² OLED which means it's probably still using an Eco² OLED Plus display. I was hoping for a third generation since they announced a brighter inner display. That probably means it's the same panel found in the Fold4 which was likely artificially limited, similar to what Samsung did with the S21 Ultra and S22 Ultra.
-The fold testing numbers are the same compared to the Fold4 found here. They did manage to maintain the same durability with a new waterdrop hinge at least.
Also if you were wondering, the Flip5 crease is similar to the Flip4, while the Fold5 crease feels a lot more subtle compared to the Fold4. I had hands-on with the Flip5 for a few days, and currently have a Fold5 review unit, all provided by Samsung.
More info from The Verge which also mentions Samsung's new repair provider Encompass.
