For sure if we count VRAM as well. Hell I've seen benches of games that go over 2 GB of VRAM alone. Metro 2033 maxed on 3 screens is doing 2.5 GB of VRAM. 

But GPU RAM aside,  I doubt games will ever use more than 4 GB of system RAM. Hell even 2 GB seems like a strech for next gen. 

Well for consoles we are talking combined and as far as memory addressing goes in applications it's all takes up address space. In a 32Bit game if it chewed through 2GB of VRAM then it would technically only be able to address 2GB of system RAM, hence why most games today (which are mostly 32Bit) won't go past ~3GB of RAM usage.

Yeah, but there is a big difference between 32 bit and 64 bit games performance. If this benchmark is any indication http://www.tomshardware.com/reviews/ram-memory-upgrade,2778-8.html  Look at HL2 32bit vs 64bit.
