Regarding importing W2 save games - per the manual (See Post # 284
[LINKS ONLY] Witcher 3 News)
Importing Saved Games
You can import a saved game from The Witcher® 2: Assassins of Kings. Doing so will incorporate the choices you made in that saved game into your The Witcher 3 experience.
To*import a saved game, click on “Import The Witcher 2 saved game” in the Main Menu under the “New Game” option.
NOTE: This option is only available if there are saves from The Witcher 2: Assassins of Kings present in the saved game folder:
%SystemDrive%\Users\%USERNAME%\Documents\Witcher 2\gamesaves
Any The Witcher 2 saved games present in that folder can be imported into The Witcher*3: Wild Hunt. However, it is highly recommended you use the final autosave from Act 3 of The*Witcher*2, as any earlier saves will not incorporate choices made in the latter stages of the*game. Default settings will be applied to any choices not imported.
If no The Witcher 2 saved games are present, a dialogue can be triggered during the Prologue, allowing you to answer questions to simulate an import of your choices from The Witcher 2
As you can see, as long as you have a W2 save game located in the targeted location, you should be able to import it into W3.
All I ask - is it May 19th yet?
Happy hunting
