From what I heard they are only changing the portal, so Everything should continue working. The only thing that may change is the EngineLTC addy... if they alter Engine.exe
On the other hand, if it is a full patch then everything will be patched, even black cipher may be detected.
@ Nubs who don't know difference between patched and detected...
Patched: When Nexon does an update and addies change, thus resulting in hacks that may d/c or not work.
Detected: When Hackshield notices a part of a code or hash in the hack and causes Combat Arms to close/ d.c..
