Amazing PSP sales, and very good CC:FF sales, but lower than expected for the amount of hw sold. It should get to ~800K pretty easily, and could sell a million, but it's going to need legs.
Strikers has sold poorly and will be lucky to break 100K, unless it gets some staying power as the end of year approaches. Housekeeping Diary is doing well and could be a big holiday gift.
I think the most interesting thing the recent Japanese charts have shown is the need for Nintendo's internally developed sw in Japan. 3rd parties can create games for specific markets, but, overall, are useless at bridging the gap the way Nintendo does to create the broad appeal, consistent system sellers, even though Nintendo has shown them the way, so to speak.
Without new titles from their internal teams their platforms stagnate, it really is that simple. Nintendo cannot rely on 3rd parties because they just don't get it, to the extent left to 3rd parties, market expansion wouldn't happen.
I think PS3 WE and DW could struggle. WE because it's available on PS2 and DW because that kind of gaming is continuing to decline. Also, I wouldn't be surprised to see Nintendo release something big, like Wii Fit or SSBB, on Nov 22 to take the attention away from Sony as much as possible.
I don't think PSP Slim has given the system much momentum in sw sales. It looks like it's primarily selling to existing PSP owners, which is expected with every revision to an extent.
Also, I can't see CC:FF being any kind of incentive for developers because it's too specific a title. It's a new game, with a big budget, 2-3+ years in development and is based on a hugely popular PS1 franchise (within a franchise). Most developers will be put off by this rather than encouraged when DS sw sales are good for 3rd parties and the system is so much cheaper and quicker to develop on.
PSP is suffering from the same sw problems GC had, certain titles sell well, but overall sw sales are poor and the competition is much more viable. There's no question about PSP being a success, just not so much as a gaming handheld for UMD titles.
