Yeah, Microsoft is probably shipping 500 units for the launch because they are so optimistic.
DS II selling near 6k on the 360 is absolutely outstanding, all things considered.
In what way is 30K on its 4th week "strong" for the PS4? Vita is doing very well considering what it tends to sell. PS4 is a major disappointment at the moment.
A) Supply is constrained almost everywhere
B) "No gamez" is perhaps best applied in Japan
C) Console market is shrinking in the region
With this level interest in the console despite good reasons for consumers not to be, it is WAY too early to call the PS4 a major disappointment right now.
