So since i've just finished with my time in Act 1 and heading into Act 2 I have to ask. With the EE just a few days away is there any point in me continueing one. Will it break my game? Should I start again? Or will it be seamless?

They changed almost the whole game (10 GB of download and such) so... there are new quests (side quests I assume), new endings, new decisions I guess. I think we should start a new game, otherwise it can be a little... buggy.
I'm waiting but CD Projekt didn't say nothing about this particularly point.

thats what I was thinking as well! Thanks for the input. Its an awsome game and im loving it so far. BTW the free backup copy i gave to a friend who showed it to his friends who then bought a copy, who's roomate bought a copy... YAY!

I tested to load a game saved from 2.1 in EE and works fine. I must say that the save is from Act 1 (Act 3 contains new quests, so maybe is trickier to load a save from that Act).
But it seems that there are not any problem with quests at all, feel free to try loading your previous saves.
