Well, I've certainly found the near-monopoly that Square-Enix has on the RPG genre to be one of the worst things to ever happen to the industry (even if I'm really looking forward to FF XIII), so if Mistwalker can finally start mounting some real competition I'm all for it. Now if only Namco-Bandai would get with the program and start really pushing the genre as it once seemed they would with the Tales series (which has since seemingly become a parody of itself). But the Tales franchise is perfection incarnate compared to what I've heard has befallen Star Ocean.
Something I'd really like to see Nintendo push for is a partnership with Atlus. Atlus already largely makes budget-tier games that kick ass and they're one of the few companies to stick with the PS2 instead of jumping headfirst into the HD consoles (Demon's Souls and DeathSmiles being the notable exceptions), so they'd fit in perfectly on Wii.
