There are a few reasons we could consider Blizzards new MMO being released on consoles.
- On all the programmer and artist job listings they have mentioned having shipped console titles as a plus.
- Blizzards Rob Pardo has confirmed that he is in talks with Microsoft over the sucessor to the xbox 360.
- All known software engineers working on the next-gen MMO have experience with development on consoles.
However, here is what Rob Pardo had to say about bringing MMOs to consoles:
Blizzard Quote: (Source)Another big issue is how to actually do patches because the certification process is pretty arduous to do that. I know that's something Microsoft is trying to work out so you can do more updates and the certification process is faster, but it's not going to be nearly as fast as we can do it. We just put it through our QA department and upload to our servers. ... Then, the other big issue is the business model. Right now, Microsoft and Sony charge platform fees for retail, but if you do an MMO there and it's subscription-based, they're going to want a cut of the subscription revenue too, and so that becomes a hurdle. So there's definitely a lot of hurdles right now for doing MMOs on a console, but it all can be overcome and I think in the next generation of consoles it'll be much easier.
It's safe to assume that if Blizzards next-gen MMO is to come out on consoles, it will not be on the xbox 360 or the ps3.
