AFAIK it has not been officially confirmed, nor has it been stated somewhere. People get the idea because the Galaxy-X already cost that amount of money which is, to be honest, a very heavy price for a single item. Considering you usually could get full scaled add-ons for PC games at a 25-30 US-$ pricerange, spending 25 bucks for just a single ship is simply overpriced.
We're still waiting for all kind of official information. We still don't know the ships specs, the layouts or the price tags. I'm crossing fingers for todays Engineering Report, maybe dstahl will give us some more information.
Thanks for that info!. That's what I thought but I could have easily missed a dev post, and wanted to ask first.
