Update: It appears that the bundle is coming to Steam as well.
Original Story (October 31 at 1:59 PM Central):
Escape room puzzlers Zero Escape: Nine Hours, Nine Persons, Nine Doors (999) and Zero Escape: Virtue's Last Reward will be offered in a two-pack for PlayStation 4 and PS Vita next spring, according to the PlayStation blog.
The package is called Zero Escape: The Nonary Games, as both titles involve nine characters who have to escape from a Saw-style series of deathtraps set by a villain named Zero, by solving puzzles and making choices between rooms.
Initially released on the Nintendo DS, 999 has been upgraded with HD graphics as well as English and Japanese voice acting.

This package includes the first two games in the trilogy that concluded with this year's Zero Time Dilemma. The graphics and VO updates to 999 are certainly welcome additions.
