Hi Kyle,
The bundle by definition is the DVDs, but you also have the ability to download if you wish. Just click on the applicable link to go to the respective download pages. I'm currently running about a week behind on DVD manuacturing, so your DVDs aren't likely to ship until late next week. I'm busy clearing a backlog and able to ship 30-40 orders a day. I hope to be back to the 24-hour turn-around by about this time next week. So, by all means, if you want to start using your new purchase right-away, feel free to download your area(s) of interest in the meantime, until your DVDs arrive.
Those DVDs you see are, in your case, for any future updates you can order updated DVDs. I merely put them on the download page for convenience. You have already bought the V2 6-DVD set.
The 4-DVD set you are apparently seeing is a typo remnant from Version 1, which was 4-DVDs. V2 bundle is 6-DVDs. I'll fix that at my earliest opportunity.
Hope this helps
