Just out of curiosity, can it do everything that the X2 can do?
Yes it can, but has extras as it has more capabilities with the 1186 chipset as presented in the teaser and added all differences I have noticed myself sofar (I might have missed some things...., so don't shoot me if I have):
+ fanless design, even with internal HDD
+ full 3D player with HDMI 1.4 interface
+ DD3 RAM vs DD2 Ram on X2 ( Twice the speed)
+ GUI is 3D when playing 3D
+ aluminium special design case
+ very easy swap internal HDD Xbay, just open te bay with a button press and swap the disk
+ remote control with active backlight and programmable hot button
+ faster boot and GUI
+ better network copy and stream speed
+ better File Manager copy speed on HDD / USB
+ lipsync option in setup (possibility linked to the HDMI 1.4 interface)
+ improved DNLA DMC Upnp feature
+ new Internet Browser (faster) with Menu options and bookmark function
+ BD Menu on/off 'F3' button
+ possibility to disable PCIE Wifi card from boot
+ x.v. color supprt
