Unfortunately, if these are the real thing, they are very uninspiring.
Xperia L is nothing more than Xperia S with slightly different SoC and the same screen.
And the same goes for Xperia SP- whats the difference from Xperia T?
They are probably going to end up being rebadged last-year phones at lower price point.
Still, I've always expected more creativity from Sony, which their new phones sadly lack.
A powerful camera-phone? A Walkman powerhouse with amazing stereo speakers? Their flagship Xperia Z ships with one of the most quiet speakers on the market.
Pity, I have always loved their phones, as I am using one.
