Using his words, people buying the A320 and similar devices want an emulator priced around $100. Any feature that significantly increases the price would make it have to compete with the other more expensive linux based consoles (Wiz/Caanoo come to mind) or with the godzillas of the market (NDS, PSP).
So, any wished feature must be such that doesn't increase the price significantly:
- Better processor: by next year, the CC1800 will be obsolete and underpowered compared to other competitors in the PMP market. The CC2000 will be a bit more expensive, but here they have no choice but to move on or lag behind. Note that the CC2000 has a powerful GPU. More details upon the official anouncement.
- 256MB: this was already planned before I suggested it. Note that the CC2000 processor uses DDR RAM, whose widespread usage makes it cheaper than the SDRAM used by the JZ4732 and CC1800. This means 256MB in the next generation consoles may probably cost the same or less than 64MB in the current generation consoles.
- A 480x272 4.3" LCD screen is not much more expensive than the A320 LCD, and it would make a big difference, at least for me. I find the A320 and GA330 screens too small. Problem here is that if you need a multiple of 320x240, you'd have to go for an 800x480 4.3", which I believe will be not just a little but much more expensive.
- It should be obvious: either powered host USB type A or SDIO. Not both. My choice here is host USB, because dongles are way cheaper and more accessible than SDIO cards. But they pointed out that it may be impossible to fit such a bulky connector in the design. Maybe the PCB cutout would solve this. Anyway, it would increase cost just a little bit (mostly due to the USB power DC-DC converter), but you are also saving by removing the 2.4GHz radio from the design, which also as I pointed out, may be a big advantage when (if) time comes to pass CE/UL certification.
- Analog nubs: if they are aiming, besides emulation, to get software studios to develop games for this console, it is a must. A GPU capable of, for example, running FPS games, would make no sense without analog nubs.
So: a CC2000 SoC (800MHz, GPU), 256MB DDR RAM, 4.3" LCD, analog nubs and powered host USB type A port. This would make a killer emulation console and stay in the same price range where the A320/GA330 are.
Camera, touchscreen, WiFi, etc, are nonsense. If you want too shoot crappy photos (most integrated cameras are crap) or browse the internet, use your phone or buy a tablet.
