Easy Tiger!
I would imagine the guys are on xmas hols just like the rest of us.
To answer. No you can't import your old save game. The all new DSK game has been remastered in every area meaning your old save would be out of place and the balance of everything has changed. There are also new weapons & armour sets. Alot is different and it's like playing a new game all over again.
You can play Flames of Vengeance without touching Eco as you will be given a character with stats close to what you might be if you did play Eco - So I believe as I have not gone this route and fully started over again which is ALWAYS a pleasure no matter how many times I restart.
