They've given an update on their Facebook page of the two products that are in development and announced that after these are released there will be no more developed. Facebook
There was further reasoning given in the comment section of the post. They are not switching to TSW; instead, they will be stepping away from train simulation altogether and moving on to other things. It seems they have built everything they set out to build, and there are too many others still developing for TSC for too few customers. I’ve always been surprised that the UK has so many different developers for heritage rolling stock, while Germany and other countries don’t have a single one. It makes sense to me, and it’s not the end of the world.
It is sad that they're moving away from TS development, but I have to say I won't miss them. I'm glad they've made some of the stuff they've done, because nobody else would. However, not much of their content can really be described as 'high quality'.
I regard DT's products as being shape accurate and with excellent texturing. They don't have all the advanced features of some products, but they always meet or exceed DTG TSC standard steam features. They are also cheaper than the advanced products and don't generally get released with annoying bugs. They might not be luxury quality, but they are certainly good quality and I tend to enjoy them more than CR's products. I shall miss them.
The textures are usually pretty poor, with the colours usually far from what they're meant to be. The physics and sounds aren't good either. The GWR Railcars were borderline okay, but there isn't much else worth getting from them. Sorry to be cynical, but I think if their DLC was higher quality it would have sold more. A lot of the things they have done are trains that deserve to be in TS. However, my attitude to DLC is that if it hasn't been done to a high standard it might as well have not been done - and so pretty much everything DT did will need to be replaced with better versions going forward.
