So can WPA2. Obviously it's more difficult but you are implying that it's impossible to crack WPA2. Any encryption method can be cracked. (Also, if you use RADIUS instead of PSK with WPA it becomes significantly more difficult to crack).
Wow, I didn't know I was implying that..... maybe I wasn't. Stop reading stuff into what I'm saying.
I'm referring to the vulnerability that has been found in WPA, not brute forcing an AP. There's also a huge difference from cracking an encryption method (or algorithm) and cracking the encryption password. As of now, WPA2 has NOT been cracked, WPA has, which is why it is recommended to not use WPA anymore.
