At least one unannounced disc-based game is coming to PlayStation 4 later this year, according to a new print ad from Sony.

The advert (above) appears in this week's issue of MCV and features the calendar of PS4 titles heading to retail over the course of September, October and November.

However, in a section labelled 'Coming Later This Year', Sony references SingStar: Ultimate Party, Grand Theft Auto V and "More To be Announced". Click the image above to see it in a higher resolution.

Interestingly enough, the same advert did not refer to any unannounced titles when it was printed in a previous issue of MCV two weeks ago, as you can see in the image below, nor when posted by Sony on Twitter.

Could the unannounced title be the widely rumoured PS4 re-release of Beyond: Two Souls?
