It looks like all new stock the official Xecuter2.3 Lite/Lite+/Pro resellers get are new revision 'B' versions (X2.3b). Apparently Team Xecuter got rid of the USB-adaptor (used to get power for the modchip) and is now using a normal point again (less problems with ground). Removing the USB-adaptor should also make production cheaper.

It looks like they take all power from LPC#6 (VCC5 - 5v) now.

Apparently only ground (LPC#2 and LPC#12) and 3.3v (LPC#9) are removed from xbox v1.5, LPC#6 (5v) should still be there. Even if not or if MS removes it later there's a big alternative 5v presoldered point on the rightside of the LPC. X2.3b has apparently been changed so it doesn't need 3.3v anymore (or they convert the 5v to 3.3v where needed).

As the Xecuter2.3 Pro weren't available yet (first stock is coming in this week), I guess the pros will be directly 2.3b. Will be confirmed later.
