Team ICO Collection "around ?25"

The heavily rumoured ICO / Shadow of the Colossus high definition PlayStation 3 collection will be released in March or April next year and cost "around £24.99", industry sources have told Eurogamer.

ICO / Shadow of the Colossus, which popped up on the website of US retailer Walmart over the weekend, will be available to pre-order on UK retailer websites in the next few days, Eurogamer's been told.

Walmart.com has the game down for a 1st April 2011 release, which we understand may be placeholder, and priced $39.82.

Sony's plan with the release is to ape the God of War Collection, a re-mastered port of God of War and God of War II on a single Blu-ray.

Team ICO Collection, which includes high definition ports of PlayStation 2 classics ICO and Shadow of the Colossus, should be priced similarly, according to our sources.

Sony's set to go big at the Tokyo Game Show this week, where we expect to hear more.

Sony told us: "We don't comment on rumour or speculation."

In July Sony Worldwide Studios boss Shuhei Yoshida said the console manufacturer is "keen to look into" converting ICO and Shadow of the Colossus to HD for PlayStation 3.

"As soon as we released God of War Collection, a lot of people were giving us suggestions, and ICO and Shadow of the Colossus, these are at the top of the list," he said.

"We are very aware, and we want to see and play in HD in the better frame-rate as well."

In June Digital Foundry took a look at ICO running in high definition via an emulator. Check out the results below.
