This was a big surprise announced alongside the first batch of RTK XIII screenshots:

It looks to have a lot of interesting elements added with a big map and acquisition system and actually comes out this year.
This has my hopes up as the original was one of my favorite RTK games (thanks to the wonderful translation I found here by Lady Wu). I suppose I can only hope this gets a western localization and isn't full of the typical free to play cliches. I am worried about that last part, but it looks like this game actually keeps story elements which isn't typical of free to play games.
