Over the course of the past week, BioWare laid out their roadmap for the changes coming with Star Wars: the Old Republic's Game Update 2.7. Now, those who are curious about the numbering scheme of updates will see how it's pretty much in line with how software developers tend to leave the really big updates and expansions for the round figures (2.0, 4.0, etc.). You can see how we're trundling along to SWTOR's 3.0. Theoretically, the use of sub-numbers (2.7.4, etc.) can ensure they can stretch out the revelation of SWTOR 3.0: the Undiscovered Expansion until sometime next year. However, I don't believe we're going to see that, because we know 2.7 is supposed to drop on April 8th, and 2.8 is supposed to drop on June 10th per Bruce Maclean's Producer's Roadmap.
