Halo 3 and Halo Reach methinks, maybe GTAV?

Halo 3...

Halo: ODST has a chance if it is succesful and advertised and bundled..

Halo: Reach will most definetley hit 10million in its lifetime if advertised as much as Halo 3. It is essentially Halo 4, but a prequel. I'm not sure how many people will realise this though considering it doesn't have a number slapped on the end and not everybody knows what Reach is.

Pehaps Forza Motorsport 3 will if again in the same situation as Halo: ODST.

Oh and Modern Warfare 2 definetly has a shot even though it is missing the Call of Duty from the title. Also Grand Theft Auto V will most probably hit 10million+ if it is ever released this generation and made more like Vice City/San Andreas.

There will be two. Halo 3 and Hexic.

Yes, poor you...

1.

One. Halo 3.

I think a platinum pricing for COD4 could help it over the 9mil mark by the end of the gen, but I think it will ultimately fall short.

ODST doesn't have a chance in hell of hitting 10mil.
If I'm being honest, I think the Halo franchise peaked in popularity with H3 and with the COD series propelled to great heights, and the Gears franchise another side attraction, I don't think we'll see another Halo title hit 10mil - so I conclude that Reach will not make it either.

Forza 3, Gears 3 and AC2 are all ridiculous suggestions.

There is nothing to suggest Halo has peaked ... you're just hoping it has.

It has definitely peaked if there are not going to be any more mainline Halo games (i.e. Halo 4). It's simple stuff. If you really believe that Halo Reach or any of the other Halo games to be released can reach 10 million, we'll just have to see which of us is right.

1 Guaranteed (Halo 3) and 3 up in the air.

Call of Duty 4: Modern Warfare 7.52 - With a platnium hits status and if the 360 has a long life span, there may be enough people still buying this game in the long run especially those that got Modern Warfare 2 but never played the first.

Grand Theft Auto IV 7.11 - While It still lags behind San Andreas and what not, GTAIV could make that 10 million mark if it ends up being bundled with the 360 system. Imagine a bundle with GTAIV! Course once it hits $20 we could see more copies fly off the shelves, similiar to GTA3 and San Andreas.

Halo: Reach - Can you say hype? With the right commercials, hype, and gamer fuel theres a good chance it could become a ten million seller in the long run, but it would take a lot of money invested into it to reach such sales status.

The original trilogy has come to a close, and now we have an expansion, albeit a supposedly substantial one, in ODST, an RTS spin-off in Wars and a new direction in Reach.

None of those 3 titles are likely to hit 10mil; Reach has the best chance but I don't see its opening matching H3 with 3.8mil first week nor do I see it having the same legs.

I'll happily eat humble pie if I'm proven wrong, but from where I'm standing (and Montana, judging by the page refresh) it doesn't seem unreasonable to make such an assessment. It's a shame then that you went on auto-pilot and accused me of fanboyism with the latter part of your post.
