The bigger issue is that Nintendo has stubbornly insisted on using the incredibly obtuse TEV shader system, making Wii (and Gamecube) programming infinitely more difficult for developers used to PC-based architectures (OpenGL). They have finally abandoned this with the 3DS and Cafe, which allows developers to port engines and code from PC-based development (PS360PC games) to those platforms. Significantly downgraded of course, but the 3DS is running MT Mobile, which is a version of the very same MT Framework Capcom uses on consoles, and it's also what they'll be using on PSV.

In case you forgot, most of the RE4 team is gone, and their Wii games are all rail shooters. It's not a matter of knowing the tech, it's a matter of being able to port the engine, which isn't just hard between TEV and OpenGL, it's not possible. Remember the PS2 wasn't using OpenGL either. Only the Xbox, Xbox 360, and PS3 have to date in home consoles, but it's easily the better system. I'm not saying they couldn't have made RE5 on Wii. They could have, but it would have taken a brand new engine and a lot of work. A lot more than it took to make these 3DS games, which look better than what we likely would have seen on Wii (certainly better than their rail shooters).

Game looks great, especially for a launch title. Not excited for Mercs 3D itself, but it makes me positive thinking how games will look later on in the 3DS' lifetime if developers push it.

I'm loving the look of it, but I can't be the only person more interested in Revelations...

Isn't there a demo for it at the end of this game? But it looks awesome! This and OoT will do me fine for quite a while

Yes.

YES.

This is what I want.

I don't understand the hype for this game tbh,mercenaries mode is not fun enough to be a stand alone game and if i do want to play that mode i can just do it on RE5 for free.

The only case in which an expanded Mercenaries mode wouldn't be worth a buy is if you are terrible at Mercenaries mode. Well, other reasons too, but mostly Mercenaries mode's enjoyment directly correlates to how skilled you are at the game.

Here's why there is hype: I can play as HUNK and break the necks of about a thousand guys in a row, and then switch over to Krauser and kick ethnically diverse zombies so hard their upper torsos explode. What's not to like?

Don't get me wrong, the graphics look stupendous. But from someone who has played RE5 inside and out It's nothing but a port of RE5's mini mercenaries game. The levels are exactly the same. Nothing for me, a huge RE fan, to get excited about.

You know there's more to development costs than that right? It's not as simple as Wii is always cheaper than HD. Wii is usually cheaper than HD, but putting real effort into a Wii game will yield costs over 15 million dollars all the same (Monster Hunter 3). Time is money too. If it takes developers a year to optimize the RE4 engine on Wii just to port RE5 for an extra million sales (and again, the port itself would take another year or so), then is that necessarily worth your team's efforts when they could be making a new Dead Rising on an already built engine which will sell 2 million units across 2 platforms (and again, porting 360 to PS3 is cheaper than porting from either to Wii). And maybe it is, but suddenly it's not so cut and dry. I'm not one of those people who thinks developers shouldn't have invested in the Wii. They absolutley should have, I'm just explaining to you one of the major factors in them not doing so, and that factor is that Nintendo chose to stick with an incredibly obtuse and ungainly architecture. 

It's well over 4 times the content of RE5's Mercs game (and RE4's Mercs game, for that matter).
