Right, my whole point about mentioning a new 50mm 1.4 at a decent price is that just about every enthusiast who owns a Canon would get one sooner or later. At around the $500 mark, even the less enthusiastic might save up money and get one, it could be a huge seller. Sadly, I agree, it will probably cost more like something around $800 or more, which again will be too much for me for a basic prime.
Sometimes I wonder if companies realize that they could sell more if they lowered the price of a item. Makes me think of Adobe Photoshop. I cant afford the full suite, and actually Photoshop does way more than I would need it to. A Photoshop version geared towards photographers for $300 or so, count me in. (I know, Lightroom does a lot of the same stuff, but you know what I'm saying).
