Haven't heard anything official, but it would be best to assume they are messing with the game to try and solve the latency issue. I, however, am still latency free on my end, so I would assume nothing major has changed (or at least anything to say that it has impacted how my fix works). Until I have a game where it hasn't worked (going strong for 2.5 plus weeks now), there is no way for me to say something has definitively changed. I would assume something will change once an update is released by EA, and I will tell you then if anything is changed. If they say they fixed it, the best option would be to go in, and delete everything and HOPEFULLY they did their job to solve the issue. If they haven't, you should be able to reapply my bandaid to play on. If it worked initially, and now you are experiencing delay, my best guess is something has changed in your router settings to prevent the IP from being blocked at all times. I can't say for sure what it is without sitting right next to you, but that would be the most reasonable assumption. Try resetting your router to factory settings, reapply your old settings, then apply the IP block again. It may be a little tedious, but the only sure way to know without having your own DNS server/dd-wrt program running on your router.
