Wii/ DS games are expected to have bigger sales , especially 1st party games . On the other hand I dont think that a lower budget Wii game is a flop if it sells 300k worldwide LTD .
PS3 : if its multiplatform than I think 400-500 k warants it a success , while exclusives need ~ 1 million LTD to be called a success .
360 : 1 million 1st or 3rd party ... thats it the expectations for the 360 are pretty big lately , especially for it beeing the software pusher in Americas .
PSP : I really cant say . People say that PSP games flop; regulary , but than usually we dont see the Others sales data , wich is by far the biggest in the world for the PSP . It seams 3rd party developers are OK with 200-300 K sales for their multiplatform games over the DS , because sequells are comming , while 500k is pretty excelent for bigger exclusives . A million seller for the PSP is allready a huge success ... so go figure . BTW : anithing under 100k wolrdwide is a flop for the PSP , but luckily Others region rarely alows this :)
