According to a report from the WSJ, HTC expects themselves to be able to sell 600,000 to 700,000 HTC Dream devices THIS year. Third party analysts had pegged the Dream to be able to sell 300,000 units, maybe 500,000 tops. So we're talking big expectations here.
We at AndroidCentral can't imagine HTC pulling this off considering how few concrete details are currently available about the HTC Dream. Plus, T-Mobile is the smallest wireless operator in the USA and the expected launch date is the END of OCTOBER. 700,000 units in 2 months of work? That's overshooting it a bit.
