Wii U may only ship with 8GB of internal storage, according to the latest report from VGleaks.

The site claims to have been supplied with the final specs for Nintendo's Wii U by an 'anonymous source', which suggest that the console will ship with a three-core 'Espresso' CPU and a DirectX 10.1 compatible AMD Radeon GPU7.

According to the site, the specs are only available to developers via Nintendo's developers site warioworld.com.

VGleaks has previously leaked accurate details about Wii U, Durango and Gears of War: Judgment.

CPU:

"Espresso" CPU on the Wii U has three enhanced Broadway cores

GPU:

"GPU7" AMD Radeon-based High Definition GPU. Unique API = GX2, which supports Shader Model 4.0 (DirectX 10.1 and OpenGL 3.3 equivalent functionality)

Memory:

Mem1 = 32MB Mem2 = 1GB (that applications can use)

Storage:

Internal 8 GB with support for SD Cards (SD Cards up to 2GB/ SDHC Cards up to 32GB) and External USB Connected Hard Drives

Networking:

802.11 b/g/n Wifi

Video Output:

Supports 1080p, 1080i, 720p, 480p and 480i

Video Cables Supported:

Compatible cables include HDMI, Wii D-Terminal, Wii Component Video, Wii RGB, Wii S-Video Stereo AV and Wii AV.

If the specs are true, the low amount of storage space would suggest that Nintendo may not be planning on pushing digital distribution as hard as originally thought.

For sake of comparison, Wii shipped with 512MB internal flash storage and support for larger SD cards.

Nintendo has yet to reveal full system specs for Wii U. The company is expected to announce European launch details this Thursday.
