I stopped by my a kiosk in the mall right down the street; and they hadn't even been told about the release date. When I asked about the price he told me that they probably would run around $300 with a $50 mail in rebate. I didn't believe him.
This morning I went to the brick & mortar downtown, and they told me the same price, then backed it up with the fact that the GS2 is still selling for $230 on contract. As for availability, he told me they were allowed to start selling them on Wednesday, and they are getting them in tonight.
Last thing he said, was that if you're trading in your last phone, there will probably be a samsung specific price promotion: ie; my vibrant is worth $70 automatically, but last time Samsung did a big phone release (GS2?) they did a $100 guarantee for all samsung devices.
I guess we'll find out soon enough.
