Can any tell me why they didnt go with tdk 100gb discs?

Hi was wondering if anyone can tell me why the forum for blu-ray finally decided to go wiv the 50gb format and not 100gb discs that TDK had prototyped and got working or are we working with the policy that some companies here would look stupid?
I have been watching and waiting on blu-ray for a while now while i still prefer blu-ray over hd dvd to have a mere 5gb xtra over the other format seems a little bit strange that they did not try to push the design of technology to its limit to make something outstanding above the rest also there is great concern over costs of discs etc with all the forums i float around 45euros for a 50gb dual layer is quite high around 31 english pounds i only say this because i really do want blu-ray to be the chosen format but i have to say honestly as someone from the outside looking in they seem to be dragging there heels and the costs of discs seem to be very high i appreicate this is new technology and yes it costs but if they dont get the costs down very fast this will be betmax vhs all over again and yet techinaclly we all know that the betamax was better but if the money coming out of your pocket is too great i can see where this will go
I mean look like it from the normal consumer point of view you by a state of the art television has all whistles and bells says its hd ready you got choice of expensive blu-ray or says hd dvd if you already got one feature which one would you buy?
anyway back to my orginal reason i started this thread i was looking at the sony bwu-100 can anyone tell me why it is the are announcing there new pc with blu-ray in it for release in the summer and yet they still cant put a date up properaly for after market drives etc this is my point info very sketchy i dont need a new pc i have a very high custom built machine but if costs for this become to high i would have to seriously consider whether i would want to spend hundreds of pounds on something that could become obsolete in a year or two just on time scale and cost factors alone i realise that the main reason it has been held back was due to copy protection reasons and alot of film studios etc where not happy with what was on offer so it is being re-written to protect them fair enough but if they dont get there fingers out quick smart the fight will be done before it has begun you would only have to look at wembley football stadium london uk to see what i am getting at takes to long and costs go thru the roof no one will hang on for ever or spend too much i dont mean to sound like im having a go just trying to make some very vaild points and these are views i'm constantly hereing around places i frequent i had similar chats with in the region of about 70 ish people and they are all thinking the same thing as me so if anyone can answer the above and inform me of something they know i would be most greatful
