I'm not too worried about the RAM, the CPU and the GPU tbh, there's obviously a lot more going on under the hood that even the most vigourous teardown isn't going to reveal. Nintendo have always released balanced systems.
Someone at Shin'en recently praised the Wii U for having bugger all latency and Ancel has previously stated that the U has almost unlimited RAM, the latter of which combined with the huge amount of on-board flash reserved for that first system update leads me to believe I'm close to being correct about developers having swapspace available to play with for memory access.
I agree. It's just disappointing for launch day ports after the promises made since one year (on the easy port, etc). And i don't know why we should be concerned for the RAM speed whereas we never heard once complains about it, on the contrary.
