There should be at least one shipped title made with LE.
Porting middleware is a much more complex process compared to a game studio (even indie) requesting a dev kit.
There are low budget debugger dev kits for 2000$ from Sony but you need reputation or at least a decent budget. (publisher)
In fact there is no way Sony will even talk to you if you are not legal registered in any form.
But it isn't that hard like it sounds. If you have done a good job and can show a good DEMO not a concept!!! you will get through this all pretty fast.
The real happening and all the conditions can not be discussed due to NDAs, but by having access to the dev network, there are many tools you can use and combine with your own pipeline.
All of them are prepared for the Cell. LE is great for an indie to get in by making a good demo version. The real product will unlikely be using LE.
But having LE in the pool of console middleware could be great. As far as I know the guys from unigine engine made it and there is no shipped title so far. But some pretty good WIP you can not see on their site.
I am confused why there still is no mod team using LE for an own great game or did I missed something? And maybe Josh should concentrate on pushing a game out and bring it on the market. If you are starting to SELL something you become interessting for them, because they can SELL something too. It's all about $$$ and you need some to get started.
You need to register a company, an office (they won't let you handeling with the dev kits at home), contracts with employes, done projects.
So guys - the dream does go on - but STEAM is your friend right now...
