"Accually it will more than likely be a new model altogother. I don't think they are going to let Sony have any more leaway in any market. But it doesn't mean that they will abondon the Advance/SP."
Yeah, that's what I was saying. Nintendo could release a new GB for 3D gaming to compete with the PSP while continuing to support the GBA/SP. So it wouldn't really be a "successor" like the GCN was to the N64, but instead, co-exist with the GBA/SP.
