To answer a few questions:
There are regular & collector editions for both PS4 & Vita (so 4 SKUs). The regular editions are $30 and are open pre-order. The collector editions are $65 and have limited quantity.
Kickstarter backers will get an email with info on how they can order the collector editions in advance. If a substantial number of kickstarter backers order the collector editions, we'll up the quantity.
The regular editions are $5 more expensive than standard LRG releases because they include a 60+ full-color manual.
GAWD, thank you for making the standard editions a preorder. That makes getting everything I want so much easier.
