According to some speculation on the Chinese website:
1. T420, it will have the following spec:
a) Intel QM67 Chipset
b) supports mSATA, but if you choose this option, you won't able to select WWAN.
c) weight is similar to T410 around 2.25 kg.
d) Have 4 usb 2.0 (2 normal, 1 is powered, 1 eSATA/p)
e) 16:9 inch LCD
f) intel integrated or Nvidia N12M-NS (whatever that is)
g) 2 x DDR3 1333 mhz ram slot.
------------------
T420s, 16:9, same intel chipset as the T420, but it will have support usb 3.0, same ram configuration.
------------
T520, same intel chipset, 16:9 LCD, 4 x usb 2.0 slot, firewire & DP support, same ram configuration as the T420, Sandy bridge i3, i5, i7. Intel or Nvidia NVS 4200M graphics (1 gigs vram), around 2.6 kg.
---------------------
X220 will have 16:9 inch LCD, usb 2.0 support only (one of a friend from Lenovo told me usb 3.0, but that seems to be a misinformation).
-------------
The expected released date is Feb of 2011, Nvidia GPU model will come out by March 2011.
