Scarlet Traces started off on some online comic whose name escapes me, but its first print run was in The Meg, so there is history there beyond the names of the creators. It also felt perfectly at home in a 2000 AD title. It ended up at Dark Horse, who produced some truly beautiful hardbacks (along with the WOTW prequel), which only now are being rivalled by things Rebellion and others are putting out.
My take on this is that it's a win-win. Rebellion gets a really first-rate property. The creators get to tell more tales, without, presumably, financial risk. (I'm assuming the same creators will continue on the project.) And more people potentially get access to an out-of-print series that really shouldn't be out of print.
I don't think it's about a lack of talent or a lack of anything else. Rebellion is a publisher, and smart publishers look around for ways to expand and gain marketshare. We've seen 2000 AD inch its way into the US market, produce some truly stunning reprint, and do some pioneering work in digital. I see Scarlet Traces as just another smart strategic move that also has the knock-on effect of potentially being great for a large number of people.
