In addition, making cheap minigame collections for the Wii and using the profits to finance their "big" projects on the PS360, which causes heavy losses, is not economically viable!

Why don't they develop "big" games for the Wii at a lower cost and require fewer sales to profit? They'd then turn a much bigger profit if that game sells a lot for the same quantity sold as the PS360 versions.

Basically he's saying:

We believe Wii owners are statistically less likely to buy certain types of (=good) games. There are just so damn many of them, that they're starting to be a viable market for virtually anything.

Or well... a viable market for at least something. Hopefully something that they put some effort into. =P

unfortunately, most of the wii's huge user base is uninterested in anything that doesn't waggle and isn't easy to understand.

^Then make a game using intuitive motion controls for various violent actions.

 Which makes the repetitive nature of GTA perfect for the Wii user base then

Common sense isn't so common.

i forgot to mention that majority of the wii's userbase also only cares about party games.

I think the funny thing is they basically admitted that up until now, they were purposely trying to ignore the Wii.

 Again, GTA will be perfect then

gta isn't a party game. its a single player experience, which is why its online absolutely sucks.
