It will most likely be powered by a 1.5GHz Qualcomm Snapdragon MSM8255 (single core), have 512 MB of RAM and come with a 3.8" SLCD. It will have dual cameras - an 8 MP shooter at the back and a front-facing camera - which will come with Skype integration as we recently learned. The growing number of leaks surely points to an approaching release of Mango and we can't wait.
