LR has been doing secondary cover releases for SRG stuff for nearly every title. Especially after the original SRG site kept getting DDOS'd when they kept trying to sell stuff early on. LR had do one of their sales, got them set up on Shopfiy and then they were there for the last 2 or so years. For whatever reason they (SRG) shifted away again to some other storefront that wasn't able to take nearly the traffic as the site got and was basically taken down immediately on opening. It took me nearly 10 minutes to get the site going and I was able to get both in my cart, only to have it error out a few times, then show as sold out, but I was then able to complete my transaction for all three titles they put up somehow. All told, that was 12 minutes into the SRG release.
If you're signed up for LR's newsletter you'll get emails for all that stuff. They didn't do a large lead announcement for Hotline Miami this time, but they did give a few days notice. I think SRG also mentioned it in their info bursts too that were on social and via email blasts.
SRG is really trying to keep to low numbers and their inserts are all numbered. It's appreciated when they're doing something a little different than the other houses that are pushing out for these small run titles.
