UPDATE 10.16pm: Blizzard has now officially confirmed its Arcade Collection, which will launch tonight for PC, PlayStation, Nintendo Switch and Xbox. (On PC, it's a part of Blizzard's Celebration Collection, which will also arrive today as a bundle on consoles.)
The three Arcade Collection games can be played in their original versions or with "Definitive Edition" enhancements that add extra areas and effects. Both versions let you rewind up to 10 seconds and save anywhere.
ORIGINAL STORY 11.20am: A triple pack of Blizzard classics has popped up on European ratings board PEGI, undoubtedly ahead of a reveal at BlizzCon this evening.
