By Flop I mean the game won't get the reviews people expected, nothing to do with sales.

You realize that ninja gaiden on xbox had 94 average at metacritic...if you are going by reviews like you say, I predict NG2 to  be second to Gears in review scores...if not number 1.

Gears/Fable/Fallout will sell 3 million+ each, with Gears selling more. They are exactly the type of product that sells.

Banjo? I'd say flop. But we dont even know what the game is yet, but I cant imaine it doing well.

Too Human is a complete unknown at this point. Some previews say it'll be good. Others are skwptical. If it's halfway decent, 80+ metacritic it does 2 million due to lack of competition.

Ninja Gaiden I dunno what to think. First was pretty hardcore. Maybe a million? More if it is approachable and it catches fire word-of-mouth wise. Not much more than a million if it is too hard.

None will flop. Mainly because they are big titles. But because 360 gamers buy everything. Seriously they must not buy anything else but games.

Flop: Ninja Gaiden II (Proably too hard core for many people)

Possible Flop: Too Human (Too much bad press even though it will go down as a really good game).

Hits: Banjo, Fable 2, Fallout 3, and Gears 2

Gears 2 will prob sell like hotcakes IMO - so def not a flop
