Realistically it will have:
- Killzone 4
- New IP
- Infamous 3 or another new IP
- Half dozen downloadable titles
Ideally it will have
- Uncharted 4
- Gran Turismo 6
- Half dozen downloadable titles
I think the realistic suggestions will still be great provided it's a good and affordable console ($400). Third parties, PS+, media functions/aps, super streamlined OS, Gaikai (meaning PS3 BC maybe), technical improvements and god knows what else are a lot of other pillars to stand on.
