You can sometimes fix it. The Vita article still states that the CPU runs at 2GHz. I tried to change that on the french version to the real value of 444 MHz, got a very bad welcoming and thus nothing changed as I didn't want to fight. I still provided several sources, but apparently Yifanlu's twitter was trusted less than bulshit gaming newsite that all write the same info without any verification of the "news".
Wikipedia is wrong on that value, and the Playstation Vita is a pretty important article.
I generaly like Wikipedia but you have to be careful. I take it as an index, like Google, with the added benefit that it was built by humans. It is my favorite source of translations as well: look for a word, change the language and you get an accurate translation.
True, 2GHz quad-core in 2011 would be exceptional; especially in a mobile gaming device that is passively cooled.
