False. Technological generation means a big leap over previous generation regardless of how you and others try to spin it.
I don't try to spin anything here. No, it doesn't. 3DS and Vita are regarded as 8th Generation - I agree that they are. Neither have a 'big leap'. There are no pre-requisites, in my opinion. Even if I considered pre-requisites for a moment, 'power and graphics' would not be a huge priority or a defining one for me, primarily because there's a chance that those 'big leaps' would've been seen on PCs for some time, anyway. I would consider other factors such as the advances in media (cartridge to CD, CD to DVD, DVD to HD-DVD and Blu-Ray, Digital Distribution, etc.), advances and realisations in controls (extra action button, shoulder buttons, Sega Activator, 3D stick, Dreamcast Fishing Rod, Dance Mats, Wiimote & Nunchuk, dual screens & stylus, touchscreen, Wii Fit Balance Board, rear touchpad, GamePad), or gaming concepts (co-operative gameplay, asymmetric gameplay, 3D gaming) to be more important. Still, 'you and others' are presuming that there will always be a 'big leap', or that 'more power and graphics' are a huge priority for all developers, and that isn't true. To my mind, it's not about the size of the leap; it's what one does with the tools that counts.
