We're not likely to see much more of this. The ISS is nearing the end of its life, and abandoning the station is becoming more likely because of the poor relations between the US and Russia now.
Also, let's face it: we hear about the ISS mainly during a story like this one. We never hear about the actual results and findings from research and experiments conducted on space missions, though we as taxpayers pay for them, and I think that hasn't helped the space program over the years. I remember there were many experiments on the shuttle that sounded fascinating, but we never heard about the outcomes. The old NASA Tech Briefs were more about the technology used, not about scientific results.
