Usa preorder-order chart show that MH4 had 153k pre-order without a release date this just can't be true since the best launch of a Monster Hunter game is 118k.

So by how much do you think  MH4 is off in usa pre-order chart

Not by much. Monster Hunter got VERY well known in the states after Tri Ultimate, also Gamestop has been advertising to pre-order it ASAP due to the special addition which A LOT of people want. It has been on the top of a lot of charts. So I honestly think it really isn't that off.

Monster Hunter 4 Ultimate didn't even released in usa,MH could end with 500k first week according to Vgchartz pre-order i see any reason why this entry would sold 4 or 5 time more then the last highest opening

By about 140k.
