Seriously... for those who really need new camera for whatever reason shouldn't wait...
7D is what I need, hence no, I am not buying A100... Even though there are alot of improvement (I think so anyway), but it won't really change the way you take pictures...
But of course, people buying things for different reason...
friend of mind just bought 1Ds Mk II, because he feels stress at work and need to spend $$$... well, works for him...
Many of us, include myself, can't really afford to keep buying new stuff because my wallet is as thin as paper liao...
As always, I think it is important to buy what you "need".
To be honest 10MP and 6MP the different is the number, but quality of the work from each photographer will remain pretty much about the same... improving photography skills are independent of the camera...
Of course with appropriate gear makes life much easier... but hey.. having $$$ in my pocket make my life even easier... hehehe... Sony is going to hate me...
If you want the A100 and have the money... then why not!! feels good to buy new things anyway...
That's my point of view... please don't take offend.. just sharing my thought...
