Oh well, it was strange that sony didn't implement already an eid5 check but, in any case, it's not really a big deal.
Dex users can still play all the games released up until now and with lv0 pwned we have just to wait for the appldr keys to be released to resign all the future eboots(see Resident Evil 6).
Plus all those people who have a nor console(like me
) can easily reconvert to cex without too many problems if needed.
