No surprise here.
$400, and it slightly loses to the 1080 while having FAR better long-term technology. This will sell well, and Vega64 should be at least 15% stronger than this!
that might be wonderful if Vega is launching at the same time as GTX1080/1070 back in may 2016. but right now we already nearing at the end of pascal life cycle. if the said feature is really important to have nvidia will have them as well. volta will be here in less than a year.
