Well, I'm kinda gambling here... I have both parallels and MacPilot and I still purchased the bundle in hope for the mystery app to be a big bam. Screenflow and Code, I'd love both, I so hope it's one of them. If it's actually lineform, I loose, I don't need it at all. But I can not really imagine that MH would put this in - it's kinda clear that the first ones to get on the deal are the loyal customers and most of them already have Vector Designer and probably don't really need another vector graphics app.
But let's see, it's fun to gamble... The curiousity about the 3rd app is definitely worth the risc;-)
And if the bonus app is something I don't need, I will still not mind having given two nice presents today... my girlfriend got really hot for MacPilot when she saw my tweaked system few days ago;-)
Anyway... so hoping for Coda....
