Robert W. Baird analyst Colin Sebastian predicts Xbox One and PS4 shortages going into the Christmas period.
Speaking with Gamespot, Sebastian said that "it is more likely than not that there will be initial shortages" due to the inherent "complexity" of a major console launch.
He went on to note, "This also partly explains why the manufacturers have been somewhat judicious in allocating pre-sale units to retailers, so that there won't be a lot of unhappy customers from day one."
"From a timing perspective, both platforms will want to launch before Thanksgiving/Black Friday, and ideally at least a couple of weeks in advance of that in order to replenish the retail channel," said Sebastian, who also thinks the console that arrives first will have an advantage of its competitor.
"In terms of who goes first, it would certainly be ideal to launch first, and gain all of the initial attention and momentum, as console launches are really the only equivalent of a 'red carpet' event for the industry," he said.
Microsoft recently claimed that Xbox One pre-orders are "trending higher" than that of Xbox 360 during its respective pre-launch period.
