- Price for Zebra2: 199$
- Price for Zebra3: 249$
- Upgrade V2->V3: 30$
- Upgrade from Zebra2 + The Dark Zebra: Free
So, hehe, it really makes a lot of sense to get Zebra2 first. For one thing it's cheaper to upgrade. And then, you have access to a few thousand presets in Zebra2 which may or may not be ported to Zebra3.
Just a note: While ZebraHZ (the "upgrade" coming with The Dark Zebra) has Diva's filters, Zebra3 won't have the exact same ones.
More facts once we know them.
P.S.: The term "started to work on" certainly means at least 6 months until we'll see anything!
*addendum: While we probably won't sell Zebra2 anymore, we will still support it for a long time. Just like we still have working builds of Zebra1 and MFM1 to ensure that people who have those can still open their projects today.
