even J Allard was telling us way back when...
Remember back before even the unveiling when he was spouting off about how cell phones were great and you got all sorts of content and services without a hard drive... I'm sure you all remember that because it made everyone think that they were getting rid of the hard drive all together... well guess what, he KNEW that they were planning on making it optional and he was hinting at it, even before the unveiling. I'm sure developers knew before they even got their alpha dev kits.
