Ninja Gaiden will not really provide much of a boost for the PS3 in North America because (for the most part) it is the same game that was released in 2005 with Ninja Gaiden Black, which was (for the most part) the same game that was released in 2004 with Ninja Gaiden for the XBox; neither of those games broke 1 Million units even though they were high quality and on a far less expensive system. In Japan I couldn't imagine this game performing on a much higher level than Gundam Musou ...

Lair's impact on sales is far more uncertain, it's pretty but has a lot of things which may (or may not) limit sales; it is not a popular genre, it is not a sequel, and it is not based on a licenced property. None of these issues means that the game can not be popular, but probably means that there is very little awareness of this game. Sony will need to heavily market this game but (much like Motorstorm) this may end up failing to attract the type of attention the game needs.

The 3 biggest summer titles for the ps3 are Ninja Gaiden Sigma ( June 3rd), Lair (july 31), and Heavenly Sword (august 7), All thre will push ps3 in some fashion depending on how they are marketed. Plus the Wii releases are expected to slow down by summer unless it is nintendo that will be releasing games. Nija Gaiden will probaly move 200,000 copies in the month and maybe ps3 sales will be around 50,000 that week, Lair will make a bigger impact with about 370,000 for the first month of release and consoles sales will be 69,000 that week, and then Heavenly sword should sell about the same with hardware being maybe 65,000. But these are just rough guesstimates but the ps3 is in for a good summer.

Do you call "1 unit" a boost in sales? I take "boost" to mean a medium/long-term increase in the weekly sales of a console. Gundam boosted sales of the PS3 in Japan - but not for long. Or to restate - I don't think Lair will provide a SIGNIFICANT boost in sales for the PS3. Its just not the sort of game Japan really cares about. The software may sell (PS3 owners looking to play something), but I can't see it selling hardware.

i think the month of july will be boosted in sales because as of right now ninja gaiden comes out july 3rd and lair comes out july 31st so i think it has potential to be a nice couple of months for the ps3 since heavenly sword is supposed to come out soon after

Why are you even mentioning Lair in japan, it has no release date there. Has it even been announced for japan ?

i think lair will do pretty good but im not too sure about ninja gaiden sigma

Undoubtedly LAIR would give ps3 a massive boost with 1.5m---3m copies in sales.

NGS at 1080p at 60fps would see ps3 hardware sales spike to 40k per week for some weeks.

as for HEAVENLY SWORD it might turn out to be the best game of the year.

Theres just no doubt in anyone's mind that starting JUNE ,2007  ps3 would dominate all markets.

dont forget a minimum of 200k sales for minna golf due JUNE in JAPAN.

at present minna is at no 8 on famitsu list.

They will give PS3 sales a boost, but not the boost that everyone expects. There is alot of Hype on these games, because FINALLY the PS3 gets some good games. They are going to be good games, however.

There sure wont be as big a boost as larry here says.

are predicting this for a short amount of time or over a longer period of time? cause if youre thinking short than up for a disapointment. sure it'll see a boost but NOTHING compared to that.

Neither Lair nor NGS will move many consoles. One is a remake while the other is a niche genre.
