360 will get a boost in July and August that because of clearance of 20GB HDD. PS3 sales will slow in July and August because of 80GB SKU replacing 40GB SKU in September (Why did they announce that..They are just asking for the public to wait).
As for E3 showing this will ultimatly help the 360. 360 did have a better conference than PS3. I believe the only game showcased for the 360 that releases post 2008 was RE5. MAG will be like Home. Something we will see over the next couple of years and wonder if it ever will come out. The FFXIII effect is to tell everyone except people in Japan that the console for RPG's (JRPGs and others) is the 360. Until the MS conference some people would still say the King of JRPGs was coming to PS3 only. Not any more. So honestly other than Japan PS3 doesnt have any game that could seriously have any effect until GT5. MS also made a good showing for the casual crowd. If "Your in the Movies" had been called "Wii Movies" the Nintendo faithful would be proclaiming it the 2nd coming. Sony didnt do anything in thier presentation around casuals.
