Side-comment: if you expect Sony to take that petition seriously, start with using proper English with right capitalisation and no mistakes.
However, if this is a rumour, it doesn't make much sense anyway.
You should also think that the USD has been strongly devalued in the last couple of years, so it may be easier for an European to buy a $300 gadget than for an American. Indeed it's actually cheaper to buy in US from Europe than the other way. For this reason Sony may understand that it would be the same economical efford for Europeans to pay $450 as for Americans to pay $300.
Hope you got me, btw, I'm not saying anyway my English is somewhat better.
