Question about steam bundles

I'd like to know the same.

No, they will not be added as a gift.

I'm sure you don't. You will get only the games you don't have to you library.

From my experience: If you add it to cart, then when you go to the payment page (before buying) it will say in the bottom if you get additional copies or not. The most likely answer imo is no.

Happens very rarely... for me it was the case with the Halflife and the Flatout bundle.

For some reason, I can't access the link, but this should answer your question:
Quoted from https://support.steampowered.com/kb_article.php?ref=4502-TPJL-2656 :
Extra copies will only be issued as a special promotion in the following specific cases:

Users who own "Left 4 Dead" and then go on to purchase "Left 4 Dead + Left 4 Dead 2 Bundle" will receive an extra copy of "Left 4 Dead".
Users who own "Portal" and then go on to purchase "Portal Bundle" will receive an extra copy of "Portal".
Users who own “Half-Life 2” and go on to purchase “The Orange Box” or the "Valve Complete Pack" will receive an extra copy of “Half-Life 2”.
Users who own “Half-Life 2: Episode One” and then go on to purchase the "Half-Life 2: Episode Pack”, “Valve Complete Pack” or “The Orange Box” will receive an extra copy of “Half-Life 2: Episode One”.
Users who own "Dawn of War II"and then go on to purchase "Dawn of War II Gold Edition" will receive an extra copy of "Dawn of War II"
Users who purchase the available four packs for specific Steam titles will receive three extra copies of that title to gift to friends.
Extra copies may apply as a part of some limited time promotions. In that case, information on what will be included with your purchase will be listed on the storefront's transaction page.

These special promotions will allow you to send a gift pass for your extra copy to a friend who does not already own the game.

These promotion do not apply to any games other than those specifically listed.

I can't view the bundle (probably not available in Germany).

But I'm pretty sure that only valve bundles add games you already own as gifts.
I had at least two bundles (that weren't valve games) that were lost, since I already had them in my library.

Try to activate it the bundle as gift (inventory) on an alt/friends account and hope that it'll split into multiple gifts.

The games that I already own, do I get them in my inventory as gifts?

simple answer = no

complex answer = only maybe 1x handful of games (mostly valve games themselves) give a gift copy if you already own it.. this post had all of them i believe..

OK as someone suggested I added it to cart & there was a notice that I wouldn't receive extra copies. Thanks for the quick replies everyone, I decide not to buy it.
