The cold truth: PS Vita sold less in one year than the PSP in 1 month

I don't think its their last portable. Sony keeps trying to continue making new products hoping they sell well. For example, their TV division has made gigantic losses but they continue to keep producing new TV's and never give up even after years of loses.
I guess they just like to continue making products of the same brand like walkman, Bravia, VAIO.
