How bad do you think the S4 sales are doing??

The GS3 sales were awesome enough for everyone to talk about them and Samsung to brag how good the GS3 sold in the opening week.... But I have heard nothing about the GS4 sales or anything how good the pre-ordering went or anything. Do you think this phone is more of a disappointment then the 4S was? But at least the 4S had a all new feature Siri and that actually mattered.

What do you think? Do you think Samsung shot themselves in the foot by almost literally making another note with extra useless features?
