If I'm a developer, which platform/s am I likely to develop for?
Fair comment. Wii has Xbox1 quality visuals at best though
Firstly the PS3 has twin 6800GTX SLI type performance. The 360 has ATI Radeon X1800/1850 type GPU. Both are old hat really. However the CPU is about the same as an AMD triple core Phenom so it isn't the CPU grunt as such either, and the G5 class PPC is not even close to the PPC performance of the IBM Xenon 3.2Ghz CPU in the 360 and even if it was OS4 can only use one core.
What IS different is the architecture of the consoles, the bus bandwidth is incredible for a start. The OS overhead is minuscule too and the hardware specification is locked. This means consoles are very efficiently utilized unlike Win7 gaming PCs.
What x1000 needed in the first place was a locked graphics card with top end specification, and then pay for full 3D driver development for that one and only 3D card specified.
As it stands the x1000 technically could never compete with even a £500 PC gaming wise, so it might get better games than SAM based machines but that's not really enough IMO.
