Personaly i'm dissapointed they did not take this oppertunity to re-design the controler from the ground up properly.
For me without doubt the PS shape and layout is the worst there is out there. Its akward to use the thumbsticks and they obstruct the start/select buttons. The d-pad is not even that good considering its central positioning. Hopefully they have atleast beefed up the weight of it.
If the PS pad is so poor then why did MS and Nintendo model their controllers on the shape of it? They are effectively the same controller just with very small modifications.
TBH i dont think the PS controller has been bettered and is the only controller i like playing with.
