“The larger 3DS format is not all that compelling for the consumer, and although I think the XL will help sales, I don’t think that the impact will revive weak sales of handhelds overall.
Vita’s too expensive for most, priced pretty much the same as the PS3 everywhere. While I think the Vita is a good value and a great device, when compared to the PS3 it’s pretty expensive.
Also, there is not much of a library of Vita games, so sales will probably be slow until we see more content.” – Wedbush Morgan Securities analyst Michael Pachter speaking to VG247.
