i mean, we all saw the videos from the announcement, and the "live" demos. and that was just pure lies no matter how you want to paint them.
also even if they didn't lie, don't we need the dev kit to have the same full capabilities as the final product? would you acquire an early dev kit for some new console, only to find out that it has less ram, gpu and/or cpu than the final product? how can we actually test it fully?
