I'm more likely to get a GameCube than an X-Box, but I might end up getting both eventually.
And Sega will always be around, they are survivors
I'm very glad that they left console development though, I was never very pleased with any of their hardware. I own a Dreamcast and it has a huge lack of RPGs. Shenmu is awesome but, again, it isn't an rpg.
Developers need to learn that RPGs (or hybrid rpg/adventure games like Zelda) sell more than most othe types of games. If a console doesn't have a healthy supply of RPGs it will die. Microsoft doesn't appear to have very many RPGs in its lineup. Nintendo will always have Zelda though.
