It's now conky -> i3bar. To enable colors, conky produces JSON output. The script i3bar_wrapper.bash handles the invocation of conky and redirects the output of i3bar to i3bar_clickparser.bash, in which click events can be handled (none implemented right now). conky/virtualarch.conky.dzen is a conky output suitable for dzen2, it should produce the same output as conky/virtualarch.conky does with i3bar and JSON.
