I think there are too many assumptions which have to be made to predict the final sales trends beyond the next few months. All we can really say is that the date which the previous market trends would indicate the PS3s LTD sales would pass the Xbox 360s has been pushed back 3-6 months. However that too is subject to change. Anyone saying anything different is talking out of their butt! 
I also want to say that the Xbox 360 S is actually more important for the EU and Japan than it is for the U.S. You have to consider that DSL and wireless are more common and physical internet connections at the TV are more limited. In addition to this the area of the living rooms are smaller in these places so the percieved difference in noise are much greater. This is why American 360 owners downplay noise and wireless as a factor and why European people do not as much. Im talking long term trends here and not the short term boost its getting due to being redesigned. Finally people in these areas are less positive towards the 360 in general so they will be far less likely to overlook percieved reliability shortcomings than Americans.
Finally the Xbox 360 is in a better medium term position to shed further costs on the console. With only one CPU package remaining they can shrink the CPU/ED-Ram once again and combine them both as ED-Ram is on a CMOS process due to the fact it also incorporates logic transistors. This means they can keep pace with any PS3 price cuts or even exceed the pace of PS3 price cuts if they so desired. However I do not forsee any changes in the new console packaging externally as at this point they can save very little here without increasing their costs in other areas like for instance going for a slimmer laptop drive.
Tease.
