I have since found the answer to this question, but I can't find the dang ol' DELETE THREAD button, so here it is anyway, with the answer for anyone who also thought as I did, at the bottom...
So I just saw the pricing scheme for upgrades from previous versions of the toolkits to the new ones...
- Music Production Toolkit to Music Production Toolkit 2 Upgrade: $49.95
- Music Production Toolkit to Complete Production Toolkit** Upgrade: $1,595
- DV Toolkit to New DV Toolkit 2 Upgrade: $295
- Original DV Toolkit 2 to New DV Toolkit 2 Upgrade: $49.95
- DV Toolkit to Complete Production Toolkit Upgrade**: $995
- Original DV Toolkit 2 to Complete Production Toolkit** Upgrade: $695
...now, if I'm a current owner of DV Toolkit 2 who wants to get the Complete Production Toolkit, would it not make more sense to get the New DV Toolkit 2 upgrade for $49.95, and then just buy the Music Production Toolkit separately for it's regular price of $395? (or is it $495? I've seen both) That comes to around either $450 or $550, whereas the 'Original DV Toolkit 2 to Complete Production Toolkit Upgrade' is $695.
Or am I missing something?
ANSWER: Aha, so I'm just now noticing that surround mixing and 128 tracks are only available in the Complete toolkit, and NOT in the new DV Toolkit. So THAT'S where your extra money is going!
