We first reported on StarCraft Remastered when it was announced, which was alongside the GSL 2017 Season 1 finals on March 26th. This was accompanied by a patch that brought the base game up to modern standards, which conveniently allows it to be multiplayer-compatible with Remastered, although skill-based matchmaking is exclusive to Remastered.
It has now been given a trailer, above, and a release date: August 14th, 2017.
As for the price? Pre-orders for StarCraft Remastered are available at $14.99 USD, although it’s unclear whether this price will stick after the pre-order period. I should note that the page states that StarCraft Remastered requires “StarCraft Anthology”. The way its worded makes it look like you need to buy something else, but StarCraft Anthology was made free with the aforementioned 1.18a patch. Basically, it looks like Blizzard is treating StarCraft Remastered as a paid booster to StarCraft Anthology, but, again, the latter is free so it probably only matters in terms of the install process. At least, that’s how it looks to me.
