1. Playstation 3 will sell at least 12.1 million units during the calendar year of 2010 (1st January -> 31st December). For figures, I will take VGC numbers (so it probably won't exactly start/finish on the 1st of Jan and 31st of Dec).
2. Gran Turismo 5 will sell at least 6.3 million copies by the end of 2010.
3. Halo Reach will not outsell Gran Turismo 5 by more than 1.2 million copies by the end of 2010. It may even struggle to surpass Gran Turismo 5.
4. NSMBWii will surpass 20 million in lifetime sales by the end of 2010.
5. The gap between the Playstation 3 and Xbox 360 will be 3.9 million (or less) in favour of the Xbox 360 by the beginning of October.
6. Nintendo Wii will not pass 83.4 million consoles sold by the end of 2010.
7. Xbox 360 will not surpass 48.3 million consoles sold by end of 2010.
8. Uncharted 2: Among Thieves will surpass Uncharted: Drake's Fortune in sales by end of July 2010 (if it happens earlier and then DF somehow takes the lead again before 31st July), the prediction is still deemed successful.
9. Within one month of Gran Turismo 5's worldwide release, sales to date of Gran Turismo 5 will have outsold Forza Motorsport 3's total sales to date (so, total Japan sales + 1 month of GT5's rest of world sales will exceed FM3's total worldwide sales to that point).
10. Splinter Cell: Conviction will not outsell Uncharted: Drake's Fortune by the end of 2010.
11. Killzone 2 will surpass 2.6 million in sales by the end of 2010.
12. Playstation 3 will outsell Xbox 360 by at least 1.15 million during the first 3 months of 2010.
13. Playstation 3 will receive a price cut or a value added permanent bundle by the end of 2010. (Value Added Bundle: 1 (or more games) or Gem/Wand/Sphere/PSWand or 120gb PS3 Slim will be replaced at same price by larger hard-drive system)
14. Battlefield: Bad Company 2 (X360 + PS3) will outsell MAG's total sales up to that date within 3 weeks of release.
15. Heavy Rain will sell under 325,000 copies first week.
16. PS3 will outsell X360 WW in 2010.
17. Wii will be outsold by PS3+X360 (combined) by at least 2.5 million WW in 2010.
18. Heavy Rain will be a million seller by the end of 2010.
19. Alan Wake will not sell more than 450,000 first week, but will sell more than 1.5 million by end of 2010.
20. Modern Warfare 2 PS3 will outsell Modern Warfare 2 Xbox 360 in Others by the end of March 2010.
21. Metal Gear Solid 4 will cross 4.5 million in lifetime sales by the end of May 2010.
22. Gran Turismo 5 will have a Metacritic score of 93+ 1 week after it launches in EU/US.
23. Mass Effect 2 will have a Metacritic score of 92+ 1 week after it launches.
24. Wii Fit PLus will pass 10 million in sales by the end of 2010.
25. Gran Turismo 5's end of 2010 sales will no more than 1 million behind the total sales of Forza 2 and Forza 3 up to that point.

Wii Fit Plus by the end of 2010? I doubt it. Earlier, really earlier.

You made some pretty obvious predictions right there.

Lol Halo Reach will not reach GT5 sales.

wat i thought of them

wheres kantors thread he made one in 08 bout 09 perdictions

Wii wont pass 83 Million but it should pass 76 million if not 79 million.

Wow that is a long list. Some of which i agree with and others that i don't.

I think Nintendo could get the momentum to stop from being outsold by that much. They'll need some big games to do it, but this is their year for that. Something to restore momentum.

I agree with most of those. I don't think NSMBW will be 20 million, maybe 15 million. I also don't think Heavy Rain will reach 1 million at all, let alone in 2010. Not because it will be bad or anything, but because its a niche game.
