No, there is no intention to replace the materials.xml file with the materials-dds.xml file, at least while there are those systems that cannot use .dds. Equally, we cannot, for obvious reasons, backport all of the new stuff in dds format to png, so over time the two files will drift further apart. There are significant gains in performance and appearance by using dds, so it's worth running both formats in parallel. The current phase of work is largely complete; I think Emilian has some tidying up to do. Apologies for the tardy reply: I replaced one of my HDD with a SSD on Christmas Day - it worked well for 3 hours or so then it all fell apart. The hardware is fine - but I'm still rebuilding all the software from scratch. I expect to have it all back by the end of the weekend. (OK, I'm an optimist.)
