With Sony releasing some very juicy details about the ps4 (I think the 8gb ddr5 ram sounds unreal), and Microsoft yet to release anything solid, do you already know which one you will get??
Are you sticking with the same brand you have now for familiarity or tempted to switch depending on Xbox specs?
Me, I had:
ps1 (loved it even when I had to turn it upside to make it work)
Xbox (unleashX, xbmc, mame, enough said)
360 (cheaper and out first)
and very tempted by the ps4!!
