Next Gen are likey if not 100% gauarateed to be released by christmas next year so unless they are making games this year (unlikey) then yes it will porbably be on next gen..
As for learning the code, well lets hope Beth learns their lession from the PS3 and doesn't decide to just copy and paste the xbox code again...
Make lite sense to release it months before next generation. Will hurt sales and dlc a lot.
As I understand next gen will be very similar. powerpc or x86 cpu, gpu, blueray, hd eiter standard or an small ssd.
Nothing is known about memory, my guess would be 4gb Interesting to see how the allocation is 2/2 would be restricting and you might end up with memory problems like skyrim on ps3
