The PEGI Rating website leaked the Blizzard Arcade Collection, then removed the page. However, it can still be found in Google Cache at the time I checked.
The Arcade Collection includes The Lost Vikings 1, Rock & Roll Racing and Blackthorne. According to the release date, it is slated for today. There is no indication whether the collection is a 4K remaster. What we can see in the rating is that it is going to be available for PC.
We’ll have to wait a few hours to find out more details.
Thanks for the tips, RedOctober.
