Game Industry Folks Siding With the Wii
Gamasutra's semi-regular feature taking the pulse of folks in the game industry turns its attention this week to the PS3 and Wii launches. From the comments submitted to the site, it seems that many industry vets are generally more excited about the Wii than with Sony's offering. From the article: "'Definitely a Wii (already pwii-ordered). The price point of the PS3 and the lack of enticing launch titles makes me as interested in a PS3 as I am interested in getting a root canal.' — Ryan Conlon, Gearbox Software. 'I am buying a Wii because Sony is too arrogant, from their dev tools to the price point.' — Ed O'Tey, Electronic Arts. 'Wii — pre-ordered. I applaud the attempt to expand and explore game interaction with the Wii. I will not be purchasing a PS3.' — Jim Perkins, EA Canada"
Show the gamers a game that makes good use of HD-DVD or Blu-Ray and they may buy some of the hype. Until then, all glory to Nintendo.

Sony's recent financials show that Sony Pictures, Sony Games, and Sony Financial Services have been sharing the load -- and the games division has been responsible for less than 1/3 the operating income the last two years, and slightly over 1/3 in 2004. For 2006, Sony Financial Services dominates their operating income.

Then, of course, there is memory bandwidth. The Cell has one memory bus to serve eight cores. In addition, local memory bandwidth for read in the Cell is 16MB/s, from Sony's own slides. Thus Sony recommends (on the next slide) to not read from local memory, but to write out to main memory and read from that. So eight cores are going to be constantly contending for the main memory bus. That is a horrible situation in hardware if I've ever seen one.
You are confused with some of your figures. Each SPU has access to 256K of local cache. This is very very fast memory... no misses. They can't directly access main memory, so there isn't really contention. However, the programming model is more complicated. Nothing console devs can't handle ;)
The 16MB/s figure (if that's correct, don't remember exactly...) is related to reading VRAM (sony confusingly calls this local memory) from the Cell, something you don't generally have any reason to do. The GPU has fast access (~20GB/s) to the Cell's memory (called Main Memory) which is much more useful. You can split up your texture usage between the two memory pools and cut down on memory contention.
Anyhow, too many winter brews, so I'll stop rambling.
