There's more retail listing-related fun this morning, as Next-Gen noticed that GameStop lists an expanded 512MB memory unit for Xbox 360.
The listing has since been removed from the site, but for a short while it allowed punters to pre-order the larger memory unit for $49.99 USD (£25 GBP), with a release date down for March 1.
When we contacted Microsoft it declined to comment on the internet listing, giving us the usual "Microsoft does not comment on rumours or speculation" line.
Still, the company is widely expected to upgrade the current 64MB memory unit - especially with internet reports claiming that it will soon allow Xbox Live Arcade games to exceed the previously-strict 50MB size limit, making them too large to fit on the current units.
As always we'll keep you up to speed with any announcements, or if any other online retailers accidently nudge the big red button.
