Yes, thanks. For some reason I thought that I would get all of my stuff upgraded with the bundle. Just for clarity - buying a bundle does NOT include an "upgrade". (which was the part that I was missing...)
It's funny, they won't let me but another bundle without purchasing the upgrade - I'm hoping that's a computer glitch...
I've been puzzling over this too, but actually I think it's not a glitch -- more like marketing.
If you try to buy any of the 3 Studio kits, you get steered over to buying an upgrade. That's because those kits are already in AD1 and buying the upgrade will migrate all 3 to AD2 (plus any other AD1 packs you may have).
If you try to buy a different AD2 pack (and you haven't upgraded AD1) it steers you to buy the upgrade plus 1 pack option. This should also get you the 3 Studio kits. But it looks like you could still buy the single pack as long as it's not something you already have in AD1.
So in a way it's more bang for the buck to upgrade and get the 3 studio kits. But I'm not sure I'm ready to spring for it at the moment.
