Much like Kameo: Elements of Power, Fable 2 ships without online co-op mode on day-one. However, Kameo didn’t promise the co-op mode prior to the games release, or talk about it in their presentations and hype machine conferences.
How does that happen? It’s easy to promise a feature but words do not make games true. More than likely the online co-op was a bit more complicated or had some bugs that needed to be shaken out prior to shipping. Microsoft is talking about releasing a patch for the new co-op play on the first week or so of the game release.
There are two options: ship a product that’s buggy and deal with the online PR nightmare with bugs and day-one patches, or, ship it without the feature and promise it early in the launch phase of the game. Once the code is complete, game software has to go through the packing, duplication and shipping phase. A lot of last minute testing can get done in the time it takes to produce the boxed product.
Hopefully Microsoft is doing some last minute testing to make a more reliable presentation of online co-op which everyone can use. However if it releases with a bunch of bugs…

Reportedly we’re going to see smaller 45 nanometer cell processors in 2009 which leads to similar cost savings as we saw in the Xbox 360 hardware. Cost savings appear on the manufacturing side, of course, along with less power consumed by the processor leading to less heat generated by the console.
Microsoft’s fast to push out their press release, probably hoping to overshadow any reports Sony may be releasing for sales numbers. At this point, we’ll have to believe their press release as fact until someone proves it otherwise; Microsoft would hate to be caught in a lie. Unfortunately, NPD figures aren’t collected in Europe so we have to wait for all the other metric gathering companies to release final December 2007 figures.
