Questions about Nintendo Pokémon Radiant Diamond & Pokémon Shining Pearl - Twin Pack

It says under the title Switch, ML. Does anyone have any idea what the ML means? Is it just the digital download and not the plastic box of the game or something?

What is the difference between the set and the double pack?

I was surprised to receive the game without a steel book. I was under impression (I could swear there were promo photos with steel book 2 months ago when I ordered) that this would come with one to add to the collection. This is just the 2 games in a carton box. Highly disappointing.

Would the games arrive tomorrow or only on Saturday if I order them today? The sale doesn't actually start until tomorrow.

Any news on the shipping date yet? I'm mainly interested in whether I can play it this weekend :)

Why is the double pack (119.-) more expensive than the single editions (59.- each) together?

Any information on when the game will be shipped out/delivered?

I see product out of stock and no delivery date, may I know if this only applies to future orders or also to those who ordered and paid 2 months ago?

Is this double pack also including the Stellbook? Or with which order do you get this ?

Does Digitec also offer the pre-order bonus for the two games?

Is this with download or do you own a game software card?
