We here at TheFeed received word from a reliable source that Activision is conducting testing for Guitar Hero IV already. The first round of testing is supposedly happening tomorrow and appears to be a small-scale test (4-6 people).
This could be testing downloadable content and the mention of Guitar Hero IV could be a mistake on the part of the firm conducting the test, but it could also mean that Guitar Hero IV may be closer than we think.
This would fit with recent comments made by Activision that Guitar Hero (along with Call of Duty and Tony Hawk) would be a franchise that is "exploited" yearly.
TheFeed is interested if this means that the plans for downloadable content support for GHIII are being put aside for another boxed release.
Activision was not available for comment as of press time, but we will update you with any statement they make on this topic.
Also, if they continue to use Roman numerals for this franchise then Guitar Hero IV will be abbreviated “GHIV”. LOL.
