[POLL] - Must Flex 5 be a complete rewrite or can flex code base be re-architectured?

[sébastien Paturel]

After several discussions about the difficulty to break UIComponent for 
example, and the whole re-architecturing of flex SDK issue.
I'd like to launch this poll to see if there's a consensus about it.
So in your opinion flex SDk:

1- Need a complete re write
2- Can be re architectured from the current code base

Thanks
