Damn them all at Sigma

I am very happy with my Canon 100L IS Macro lens. Not intention of getting another macro lens, do find that sometimes a bit more reach would be helpful, but I work round that.
Then what happens I see this on the news page

The only good thing about this for my bank balance, is that it is not released in the UK yet. When it is available in the UK I am praying for some really bad reviews of it to put me off. Guess I am going to have to start saving as it looks like it is going to be a great lens.
