Maybe it's just me, and I know this may be treason to some, but why does this lens not excite me on whit? Why do Canon's new baby flashes not excite me one whit?
Well, I can see the lack of excitement over the baby flashes, but this lens? The ONE? The symbol of optical superiority that speaks 'Canon' without question?
Heathen! Scofflaw! Philistine! I hereby wish eternal malfunction on your vibration reduction lens(es)! 
The 580exII needs replacement big time. The SB900 stomps it.
The 200-400 Nikon, which I owned, was nothing to write home about. Very front heavy, extremely stiff zoom ring, and okay IQ.
This one will be better. Well, I hope that it will be anyway. Very useful range for me, that is for certain. And the built-in teleconverter - I had to think about that for a minute or two, but I really like that feature.
And why can I not get excited about a lens for $7,000? And you can bet your bottom dollar that's how much it will be. You're totally deluding yourself if you think any cheaper.
I currently own 5 automobiles ranging from a 2011 Lexus SUV, 2009 Acura SUV, and on down the line.
Why would I rather buy a used Honda Accord than drop seven large on a damn lens?
Are there that many pros out there ready, willing and able to drop that kind of cash?
I guess so. For if not, Canon better do some price dropping.

It'll probably start at $8500, then drop into the high $7000 range after 6-8 months. Pending any bad news regarding its performance, I will probably have one before the end of the year.
