Only if rc4 works, i hope that. but rc2 fail ad rc3 fail two times. RC4 please make me happy

RC3 was reverted once not twice -- it is now working with 99% pool compliance. RC4 is also a "spork" -- i.e. even if enforcement causes problems it can be turned off seamlessly. I really don't think there is much to worry about in terms of RC4 "not working".
I don't think RC4 will use enforcement(spork).
RC4 would be timed-fork(enforcement on), and spork would be used for failsafe.
Is that a guess or has that been confirmed somewhere? Could have sworn I saw eltito say the opposite.
Just a guess.

LOL

Addendum: To be clear, the question on everyone's mind in regards to the Masternode enforcement mechanism built into RC3 is, "Why don't we just flip the switch?" The answer is that RC3's enforcement mechanism has caused issues on the network twice now. Knowing that, enabling it a third time in its current state because we're annoyed by some non-paying pools would be quite irresponsible. Instead, Evan has chosen to build a simpler, safer, new enforcement mechanism, to be implemented with RC4. --Chris Rimoldi (eltito)
