Badminton England chief executive Adrian Christy believes Britain's best have shown in the past week they can deliver at the Olympics.
The host nation failed to get any players past the quarter-final stage at the Yonex All England Championships in Birmingham but there were a number of impressive performances during the week.
Top men's singles player Rajiv Ouseph beat former world number one Peter Gade in the first round before the effects of a match that finished at around 2.20am took their toll in his next match.
Last year's World Championship silver medalists Chris Adcock and Imogen Bankier beat top seeds Zhang Nan and Zhao Yunlei en route to the mixed doubles quarter-finals.
Veteran Nathan Robertson also rolled back the years as he and Jenny Wallwork reached the same stage of the mixed event.
The performances have fuelled optimism ahead of London 2012 and Christy said: "Once again Chris and Imogen showed they can really deliver on the world stage.
"Home support, no doubt, helped them but they have shown when the big events are here they have the ability to strike. Their first-round win was just sensational.
"Jenny and Nathan are absolutely coming back to top form and they had some superb performances before they went out to the eventual champions.
"Rajiv's win over Peter Gade was also a real highlight."
