So, you remember that recent Xbox console update we mentioned yesterday? The one that happened on Wednesday and included original Xbox achievements? It seems like there's at least one more hidden feature to be discovered.

A couple of eagle-eyed Xbox fans have spotted that the patch notes had been adjusted for this update last night, and they mentioned that three classic startup animations were being added to "celebrate 25 years of Xbox history".

The three animations are for the original Xbox, Xbox 360 (2005) and Xbox 360 (2010).

Since then, the patch notes have been adjusted once more to just reference "miscellaneous" improvements, so it seems like they jumped the gun slightly and were supposed to wait until November 15th (the date of Xbox's 25th anniversary) to reveal these three startup animations.

None of them are live yet by the way, but it might be worth checking the "Startup" section of your Xbox console's Settings menu periodically over the next couple of days to see if they show up.

I don't know about you, but I'm going to be rocking the original Xbox startup animation as soon as possible!

Here's a look at what you can expect from the three animations when they become available:
