According to a memo distributed on Monday, Condé Nast is getting ready for four more digital magazines in a “research and development effort” that should last through October.

The initiative expects to have an iPad version of GQ available with the April issue, portions of which were shared with Wired. com by a Spokesperson. Vanity Fair is scheduled for June, with The New Yorker and Glamour following as swiftly as possible. Of these, only GQ is already available in digital form, as an iPhone app. Wired magazine’s tablet edition will debut with its June issue.

Some believe that the “magazine experience” would have to be severely compromised for a screen as small as that on the typical smartphone.

Condé Nast publishes 19 magazines and Condé Nast Digital runs 27 sites, including Wired. com, a separately-produced news service.

Meanwhile, Condé Nast Digital is using technology and techniques developed in-house to generate the digital versions of GQ, Vanity Fair, The New Yorker and Glamour.

The memo says, “We have learned from Wired thus far that adjusting to the new workflows required for digital magazine production is extremely time consuming. Only by beginning now could a magazine hope to be ready for a fall launch, should our R&D program point us in that direction”.
