A couple more reviews have appeared, on epiGamer and ActionTrip, giving the game 9/10 and 92/100 respectively. Both reviews are obviously calling JKII great (ActionTrip gave it their "Editors Choice" award), but both cite gameplay bugs and shortcomings that hold it back from perfection. Patch, anyone?
Also, there's a JKII cheat list for those that don't know them already up at cheathappens.
