Up Converting and real Blu Ray are not even in the same galaxy
If you have a true 1080p TV ( not 1080i) then the most impressive thing you can show any chick is a movie on a large screen in true hi def
We also have all 3 and in all honesty... the wii is the weakest of the three. Its cool for something like 5 mins and then you realize its a waste
The PS3 on the other hand had games that are designed in true 1080p that will knock your socks off
Dead Space on a 73" HD
every night
Get the PS3, get GH world tour and an extra guitar for when friends are over.
Bottom line... up converting is a complete joke as someone else said, there is no way to add data that does not exist
