I mean... lets look at the facts....
1) HD games are expensive. Even a regular HD game is going to cost you a large chunk of change.
2) Being expensive these systems need a lot of sales to make back the money. Hence the need for "Sure to hit" properties.
3) Companies need to diversify their products and offer on different systems so they can maximize sales.
If you took all the blockbuster games off the HD systems, you'd just be left with average games... unlikely to make back their money, and even worse, highly prone to totally flopping and costing millions.
Seems stupid.
I mean, even if the big blockbuster games don't make back their money... you know they have guranteed sales and are going to come close.
I mean, the PS2 is a sinking ship, so you can't tie to that much longer.
The PSP and DS are there.... but not everyone can retool teams to make successful DS games and who knows about PSP... how long will it last... will my game sell?
It seems to make sense to me anwyay.
Sure a lot of people need to improve the quality of their Wii games... but i'd argue that Wii isn't really where the blockbusters should be. Those should be off covering their back while they develop new ips and mid range ips on the Wii and make the successful ones their own Wii blockbusters.
