To further KDR's comment, we have these two stats from the survey:
- While 48.54% are unphased, 32.52% of those survey were less confident with the PS3 after its E3 showing.
- 62.13% feel the PS3 won't reach its goal of 6 million units sold by March 2007.
So technically only 62% said it won't sell well. The other stat there is probably the most interesting though, because it gives you an idea of whether or not that developer might withdraw some support. About 1/3 are "less confident", which is pretty high, but that means that most developers are still confident (maybe even more confident, where's that last 20%?), and the phrase "less confident" is pretty weak, it hardly translates to, "We're withdrawing support". It means that up to 1/3 might be thinking about withdrawing support, but most of those probably won't until they start to see actual sales figures.
Edit: My personal prediction (not that it matters

) is that the system will sell 6 million by March. It's after that that things may start to get hairy for Sony, unless some major game releases happen by April.
