According to reports, the PS Vita v1.69.1 update only fixes some stability issues and problems when playing the Escape Plan demo and weighs in at 97MB in size.
To quote: "Earlier today a new firmware update for the PlayStation Vita was made available. Firmware 1.69.1 can now be downloaded via wifi, PC, or PS3 to your Vita. The update is 97MB in size and takes about 2 minutes to download, followed by a minute-long install.
Firmware 1.69.1 fixes some stability issues and problems that Vita owners have encountered when previously playing the Escape Plan demo, so that explains why the file size is so small.
Unfortunately, still no PSOne Classics support so we'll have to wait a little bit longer for that firmware. So this quick update wasn't bad at all, and I personally enjoy updating my Vita since it's so fast."
