Good games.

Uhhh... PS4 isn't gonna use a disc drive.

"Sony buying streaming game service Gaikai for $380 million, to establish 'new cloud service'"

Its all gonna be on teh cloud!

Good games.

A solid line up of games and a good price tag.

just show me uncharted 4 in 4K and its a buy to me.

Keeping the system under $500 AU

I think it will all be on the cloud. Literally every PS4 game will be available digitally... Along with every PS, PS2 and PS3 game.

Maybe not every previous gen game... But yaknow what I mean!

On this subject, actually. If they do indeed put every retail game on the cloud/PSN... They need to be viable. They need to be cheaper than at retail. The prices for new games on PSN (And competing services) are horrible. They should be £10-15 cheaper than at retail.

PS4 games - £30-35 for NEW games
PS3 games - £15-20?
PS2 games - £10-15?
PS games - £5-10?

I think that would be great.

Keep the free online gaming options. Keep PS Plus options for great deals. Expand the media applications, like how Microsoft did with the 360. Bring full "backwards compatibility" using Gaikai.

I also think they should stick with Bluray. Instead of bringing us another new disc. Instead, focus on what I posted above as Internet speeds are getting better and better as time goes along. More people are getting connected as the day goes by. Digital Distribution is the future of the industry.

Fulfilling their promises. Don't over promise and under-deliver.

A competitive price point that doesn't put it out of the reach of most consumers and enticing games from first and third parties.

These bragging rights:
1. More 3rd support than Wii U and more future proof than Wii U
2. Some component hardware that on paper is vastly superior to xbox720

And Europeans sick and tired of playing second fiddle and will support whichever of the 3 the US and Japan do not support most.
