I'd hazard a guess it will be a good bit cheaper than the PS3 was when it was first released, if the whole "we're not aiming for making the most powerful console" is anything to go by.
Comically priced the PS3 definitely was when first released, and there was people stupid enough to actually buy it when it was first released with a 65 gb hard drive, although there obviously wasn't many, it was dropped almost a third in price pretty quickly, and came with a free game when the price was first dropped in most stores. Albeit with the ps2 chip removed so people wouldn't continue buying ps2 games and play only them on it cause the selection of games at first on PS3 was atrocious. The launch titles better be good this time too, we all know how bad the selection of games was on the PS3 for the first while.
The first uncharted was really green, nothing but green, nothing screamed next gen about it either at the time, they made up for it with the sequel though, but seriously, no cop out everythings green game again, and people complained about how grey gears of war was as an xbox launch title.
