The trend for Pascal seems to have reversed in 2009-2010 (with D2009 being the first version "usable" since D7?), but this wasn't really noticeable until end of 2011.
(ohloh does real-world activity stats on open-source projects, it's a better trend indicator IME than TIOBE f.i.)

That said, if the commits went up, the stats for new lines of code added didn't went up in the same fashion, indicating that the activity is probably centered around bug fixing and porting the code to the new compilers/platforms. So not exactly a revival, but better than letting the code rot away!

PS: I registered your Google Code SVN in ohloh, its commits & code will now contribute to the Pascal popularity statistics ;-)
