He also hinted that the design of the new phone will herald a new era of more attractive Windows Phone 7 handsets as Microsoft looks to take on the incumbent smartphone brigade and fulfil the predictions it will be the second biggest smartphone OS provider in 2014:
"[The new Samsung phone is] very thin and light, and that's a theme we're going to see for Windows Phone 7 devices.
"As the processors get [smaller], battery life improves and the screens get better, we're going to see phones with phenomenal screen resolution, a great battery life, meaning lightweight devices across the phones."
Guggenheimer also previewed new phones from Acer, Fujitsu and ZTE - highlighting the differences the new brands would bring.
He was most effusive of the Fujitsu brand, showing the 'fun pink' chassis, and showing off the waterproof exterior with a "great camera".
He also lauded the fact Microsoft had signed up big manufacturers like Acer and ZTE to be part of the new WP7 family - but gave no idea of what alternative configurations the new phones may offer.
