According to the latest post on PomPom Games' site, the PC versions of Astro Tripper, Mutant Storm Reloaded and Mutant Storm Empire are done and awaiting a final test phase before release.

This was cited as the reason for the delay as well, because testing these games on all sorts of different PC configurations can be pretty expensive - hence they've suggested the idea of putting out pre-release builds on their site to purchase at only $5 (cost inclusive of final version and future updates), so that interested buyers can help them test the full games out.

All they're asking is for some feedback on whether to proceed with the plan or not, and if things work out those of us who do not own a console should be able to get our hands on PC ports of their recent games very, very soon.
