A Deutsche Bank securities analyst Jeetil Patel points out some interesting facts about the sales of the current gen consoles. He points out the lack of sales on both ends the Xbox360 and Playstation 3.
Jeetil Patel talked about the Xbox 360 and PS3 and their problem with lack of demand:
"Next-gen hardware sell-through of 700K units in Feb-07 brought its total HW installed base to 8.0mn in the US, still 30% less than the prior cycle at 11.2mn units at equivalent stages. Xbox 360 (230K) and PS3 (130K) unit sales were below expectations of 250K-300K and 200K respectively. Retail checks reveal that ample supply exists, suggesting a demand problem for next-gen consoles."
He also goes on to compare Xbox360 sales to original Xbox sales.
