I think it's safe to say, Infamous outsold Titanfall in the UK (so far). http://www.psu.com/a022910/inFAMOUS--Second-Son-sales-drop-67--in-UK-still-holds-top-spot?page=0
Uhh, no. TF outsolds ISS 2-1 launch weeks. Both then dropped pretty similar second week (73% TF, 67% ISS).
In fact I'd make a strong wager TF will be ahead of ISS in next weeks charts. It should have been quite close this week.
You can see it clearer on the individual SKU chart, where TF actually rose from 3rd to 2nd.
