Ariel Sharon was about to leave Road Map?

I heard that right before his mive stroke that left him pretty much a vegetable that he was planning to get rid of the Road Map to Peace and create his own. I heard this on Yahoo news but before I could save it or send it to my email there was a problem with my computer and I had to restart. I tried looking for it again but could not find it again anywhere. Is this true and if so where can I find an article about it? Thanks.
