I think Titanfall has the broader appeal. Its a shooter and it has a nice twist to the generic mp gameplay that we get every year with COD.
Infamous looks really good and its perhaps the most "next gen" game of them all so far. Open world with beautiful visuals! If Infamous gets good reviews and good word of mouth it might be able to put up a fight. PS4 also seems to have the edge with regards to hype and support for the platform so that will help as well.
I think both MS and Sony have done well to hype these games up. The games now need to deliver.
I got a bad feeling about Infamous though...
