Senior regional director of Microsoft UK Neil Thompson has told MCV that the recent price cuts are the opening gambit in a peak season which will see "tens of millions" spent on marketing the Xbox brand.
"We've been talking to all of our retail partners about what we're doing at Christmas and we've been very bold and ambitious about how successful we think we can be.
"On marketing we'll spend tens of millions - we're going to engage in a very bold promotional push from now until Christmas."
Thompson also ruled out shortages of the console as sales begin to climb - stating that there will be plenty to go around:
"I have been very bullish on supply for the UK market," he added.
