Let's review this blog below I posted an year ago, BOLDED are the ones I got right:

By the end of 2007, worldwide sale of console will be Xbox 360 (19 Million), Wii (18 Million), PS3 (9 Million)

Halo 3 will be the biggest selling game for a single platform, and Grand Theft Auto IV will be the biggest selling game overall.

Game of the Year will be between : Spore, Super Mario Galaxy, and Halo 3.

More PS3 and 360 exclusivegames will go multiplatform : Virtua Fighter 5, Tekken 6, Lost Planet, Mercernaries, Gundam Warriors

Next wave of Wii games will look much better than what we are seeing now, as developersnow have time to polish up the graphics after they are finished with theirwarm upon the control.

Xbox 360 price will have $100 price drop on each configuration (around May), and Wii will go down to $199 without Wii Sports pack-in (September).

New PSP with harddrive will be announced, with the current price tag. And the old version will have $50 drop. DS Lite will drop to $99 and it will sell like crazy.

Prepare to see a lot of PS2-PSP-Wii ports. At first we will see a lot of PS2 to Wii ports, but later on we will see Wii to PS2 ports instead.

After Lost Odyssey released in Japan, X360 will be be finished over there.

Lots of homebrew online games will be available for the Wii opera browser and it will become very popular.

More intesting channels for Wii that incorporated with games (like the current Mii and Forecast Channel). Xbox Live will integrated even more will Zune, PC. PS3 network will stay the same with no surprise.

MGS4 will get beat bothin sale and popularity by Halo 3 and Smash Bros Brawl, as the latter two will focus on multiplayer and help spread the words for the consoles they are on.

Game Announcement in 07 : NiGHTS 2 (Wii), Metal Gear Solid 4 (360), Starcraft 2 (PC), Starcraft (DS), Kingdom Hearts3 (Wii), Ninja Gaiden 2 (360/PS3), God of War 3 (PS3), Fire Emblem (DS), Call of Duty 4 (PC), Guitar Hero III (360/PS3)
