New compact Sony Ericsson slider spy pics

Now, that annoucements are long over...here is yet another leak. It is nothing big like the P5 but it is still interesting nonetheless. The following live spy pics are from the folks over at se4m. The device appears to be of a mid to low end compact slider with a RAZR like keypad. The design (with the brushed metal) reminds me alot of the P1. I wonder what that bulge/hump is on the back...ability to use normal AA batteries perhaps? All in all, the device looks pretty slick. Enjoy the pics.
