"PS4 software combined with Xbox One software sales are up over 40% compared to sales of the PS3 and Xbox 360 through their first six months," Callahan continued.
"Wii U software sales were up over last year by over 80%."
Elsewhere, Microsoft sold 71,000 Xbox 360 consoles in April, 447,000 Xbox One games and 2.2 million Xbox 360 games, giving it a combined retail market share of 53%.

Facebook is trialling a new iOS application with a card-based interface similar to Google Now.
The app will serve users with contextual content recommendations after they check-in or post on the social network, according to TechCrunch.
The software is apparently being tested by a select group of users, providing them with relevant information about nearby places and events.
Facebook has also included some Foursquare-esque features in the app, with a colour-coding scheme showing users which of their friends have recently checked in at places in the vicinity.
The company is yet to reveal whether it is planning to distribute the context cards to a wider group of users on iOS or expand the trial to other mobile platforms.
Last week, Facebook shuttered its Poke and Camera apps.
Samsung will launch its competitor to Google Glass in September, according to a report.
Business Korea claims that the so-called 'Gear Glass' will be powered by a next-generation version of the firm's Tizen operating system.
The device previously emerged in a patent filing under the codename of Earphone, which could indicate that Samsung plans to include mobile phone functionality in the product.
Gear Glass is expected to consist of an earpiece with a heads-up display, with previous reports suggesting that it will be more powerful than Google Glass.
Samsung has been tipped to showcase the gadget at the IFA trade show in Berlin this September, but is yet to officially confirm its existence.
Google Glass went on sale in the US today (May 14), with a UK release date yet to be confirmed.
Apple is reportedly planning to include support for high-definition audio in its next mobile operating system, iOS 8.
Japanese blog MacOtakara claims that HD audio will be a key component of the software's media playback push.
The news follows reports that Apple is on the verge of acquiring audio firm Beats Electronics in a big-money-deal.
Adding support for HD playback to iOS 8 would require Apple to develop new headphones - potentially made by the Beats hardware team - as well as revised Lightning connectors.
Recent reports suggest that iOS 8 will adopt the split screen approach to multi-tasking currently seen on Windows 8, with users able to snap two applications alongside one another.
Leaked screenshots of the software suggest that it will feature a similar design and layout to the current-generation iOS 7, with a new app called Healthbook offering fitness services.
Apple will offer a first look at iOS 8 during its Worldwide Developers Conference on June 2.

PlayStation 3 games have reportedly been spotted on the PS4 store.
According to GameInformer, the PS3 games can be found under the Day-1 Digital section of the PS4 PlayStation Store.
