According to my update book, the Digi Series is just a Nordstrom Collection. There's no mention of it being released in stores, as the largest part of the collection (The make-your-own palette portion) is something you can already do at MAC Stores.
If you will check out temptalia, I sent her all the information for ALL the collections in the Update Book.
There are 7 Dazzleglasses and 4 are new colors:
Boys Go Crazy: Deep amethyst
Fabulous Fun: Rich magenta
Hi-Falutin: Light yellow pink
You Got the Look: Yellow Nectarine
Also, Dazzle Lipsticks are the same coverage as a Frost Lipstick.. so more than Lustre and Glaze but less than Satin, Amp. Creme.
