Retail availability is quite poor for Bone, but the CEX markup is £145 (33% over retail price) vs £170 for PS4 (49% above retail price), which indicates it is slightly more available.
It's an interesting question though. 360, PS2, Wii and PS4 were all extremely supply restricted in the week after launch, I don't think the situation is as bad as that for the Bone, it doesn't have full retail availability, but I also think it can be found if one's determination is there, which doesn't really seem to be the case for PS4.
So, considering this, One's second week doesn't sound that good, after all.
