CI 2.0??

[eluser]philmctim[/eluser]
Sorry if this is a much-asked question - I promise I did a little bit of searching at least without turning up an answer...

I noticed on Amazon that there is a book due for publicication in the summer (2009) titled "CodeIgniter 2.0".

So is there a big new release upcoming? Is there anywhere I can get some insight into what is planned for 2.0?

Thanks
