Freedom 3 sold less than Freedom Unite on PSP.

PS2 hasn't had a MH title since 2006. 

MH4 Ultimate is just an upgraded MH4.  It's not a new title.

Monster Hunter 2 on PS2 outsold Monster Hunter 1 on PS2. In 2006, the generation was over with all 3 consoles out. MH3 was coming to that platform.

Monster Hunter Freedom 3 sold 4.87 million retail on the PSP. Monster Hunter Freedom Unite sold 4.13 in Japan. Unite had higher worldwide numbers because it was actually released worldwide. Freedom Unite is actually Monster Hunter Portable 2G, as it was released in Japan. MHP2 did 1.75 million and 2G did the aforementioned 4.13 million.

Its hard seeing DK so low. Tropical Freeze is arguebly one of the best 2D platformers out there. It'll definitely do 1.2mil-1.5mil lifetime, im hoping SSB pushes Hardware so people can expand and get on with the best 2D platformer on wiiu :)

Yeah DK's poor sales really confuse me. I guess Im partly to blame though, I am yet to buy it because never finished Returns

So you admit a follow up on the same console still sold less than a previous title.  And the changes from Portable 2nd (Freedom 2) to Portable 2nd G (Freedom Unite) were actually a big.   MH4 Ultimate is largely the same game as MH4 with a few minor changes but now with a global release.

However, if you take Capcom's official figures into account, it is true that no MH game sold less than a previous iteration.   Because VGC has Freedom Unite/Portable 2nd G massively overtracked.  VGC says 5.42 million.  Capcom says 3.7 million.

Don't forget, MH4 never had a release outside Japan.  MH4 Ultimate will.  So Japanese only pre-orders alone do not indicate a reduced level of sales overall.

We're talking about Japanese pre-orders so the only relevant thing is Japanese sales. Freedom 3 would have easily outsold Unite had it been released in the West. By comparing one region to WW sales, you're not comparing apples to apples. When takling about a decrease, I'm only comparing the Japanese sales, because that's what matters for MH.

As for undertracking/overtracking, VGC combines all of "The Best", etc. and other re-releases into the same listing, whereas I believe Capcom has them all separated. MHP2G was re-released more than once.

How much will that will sell Hyrule Warriors in the first week?

Not bad Hyrule Warriors.
Now, next game is Bayonetta 2.
