Gamespot released a video of the, unboxing the new ps3 super-slim and it looks super cheap. For one, it has a sliding top to insert your disk and it sounds very plasticy. I, personally, like being able to insert my disks no problem without pressing noisy buttons. Second, it's small, super small, and it looks pretty cheap. Even the slim looks better. It's part glossy as well, for those who hated that from the first ps3 model will half hate this one.
BUT that is just my first impressions. Maybe it's better hardware wise, who knows?
For the 500GB it will run for about $300 and for the 250GB it will be $270. If you want a new ps3 and you really like this model, I say drop the extra $30 for an extra 250GB
