It's part of the debate going on about what elements new IPs need to succeed on the market this generation as opposed to a raw new IP count, hence the listing of what each one is.
If we compare to your list, there are actually some notable trend differences. A lot of those lacked multiplayer and/or weren't open world, and several were being sold on the strength of a short-ish linear campaign.
The last gen list had 3 online shooters, a Bioware RPG that could have easily been KotoR3, Rock Band, Assassin's Creed and Bioshock (both long by today's standards and easily marketable being GTA-lite-with-knives and shooty shooty with pretty graphics).
Dead Rising/Crackdown/Darkness/Lost Planet I'm not sure deserve the mention because none of them did anything to the market. Looking up numbers I don't think any cracked 3 million either. Crackdown might have paved the way for Infamous/Prototype but those were probably in development before Crackdown's release. And Crackdown was again bolstered by Halo 3 more than anything else (even though I loved the game personally).
I honestly don't see much difference. Only MP sells unless a beloved dev makes an open world game that is hopefully an RPG unless the game is easily marketable and has guns. Now we expect RPG mechanics and persistent characters in everything, which has been true since CoD4 hit the scene.
