Although commits could indirectly imply the popularity of Pascal, I don't think it's an accurate measure as they are many more closed-source projects that are not being monitored.

This kind of proves my above point. Delphi 2006-2007 was a huge jump since Delphi 7 both in language and IDE features. Delphi 2009, 2010 and XE weren't really big improvements, besides compatibility annoyance of forceful introduction of Unicode. Open-source trend in 2009 could be mostly due to delayed reaction to free versions of Turbo Delphi and growing community of FPC/Lazarus.
