Ahead of a scheduled press conference in London on Tuesday, Nokia has sparked speculation it may be about to reveal a 41MP Lumia thanks to a teaser ad aired on UK TV last night.The spot  which was broadcast in the middle of The Inbetweeners Movie  featured the tag 'more than your eyes can see', and appeared to depict both the lens and the flash of an unannounced device.It suggests Nokia may be about to equip a new Lumia with the 41MP camera it originally fitted in its 808 PureView  a Symbian device launched in 2012 that served both as the platform's last flagship device, and also as a handy test bed for future handsets.Indeed, such chatter adds weight to talk of a supposed new flagship from Nokia - dubbed the Lumia EOS, or Lumia Catwalk by others - is pending, with the Finnish firm having invited the press (including PocketGamer.biz) to see the 'future of Lumia' at a press event in the UK capital tomorrow.A somewhat less exciting theory is that both the ad and the event could be pointing towards the launch of the currently US-exclusive Lumia 928 in Europe.Expect the pieces of the puzzle to be revealed on these pages when Nokia takes to the stage on Tuesday.
