Will this run next gen games?

Okay, so I built my own gaming PC about 6 months ago or so, and it runs great with most of the games I've played on it. But next-generation games are coming, and I don't think its gonna be able to do the job anymore.

Here's its current specs:

Sapphire Radeon HD 7770 GHZ 1 GB DDR5 HDMI/DVI-I/DP PCI-Express Graphics Card 11201-17-20G

AMD A4-5300 APU 3.4Ghz Processor AD5300OKHJBOX

Western Digital Caviar Blue 500 GB SATA III 7200 RPM 16 MB Cache Bulk/OEM Desktop Hard Drive - WD5000AAKX

Corsair Builder Series CX 430 Watt ATX/EPS 80 PLUS (CX430)

Corsair Vengeance Blue 4GB (1x4GB) DDR3 1600 MHz (PC3 12800) Desktop Memory (CMZ4GX3M1A1600C9B)


So will this be good for the next gen games? If not what will I need to upgrade? Thanks in advance :)
