Newer mod post on the forums says the process is about to start but it may not actually appear for another ~3 hours.
Weird launch.. seems like it should have appeared in the launcher some time ago, had a pre-load, an official stated release date/time listed there (all it says in the store is by the end of August), etc. A bit outdated to just have people waiting around for it to appear at some random point. Oh well, doesn't matter long term and I wouldn't be playing it until the evening anyway.
Watching some 4K clips I think the remastered graphics are a bit hit or miss depending on the map, exact units in play and such. Some clips look great, others a bit off. Regardless, was an easy buy at $15 and I'm looking forward to trying it out. I never finished the campaign playing the original release, and am curious how I'll fair at trying out the MP matchmaking. Decent enough at SC2, but mechanics weren't my strength and obviously this is much less streamlined than that. Really just did some misc. custom games at the time.
