In an interview with the GITEX newspaper, HTC Executive Director for the Middle East and North Africa announced that HTC will unveil the HTC Shift and four brand new products at the upcoming GITEX tradeshow, running September 8 to 12.
Aside from the HTC Shift Windows Vista-based UMPC, it is not known what four other devices will be announced by HTC. But previously leaked roadmaps (here and here) suggest we could see announcements for the HTC S630 (which is already out but still has not been formally announced), the HTC Nike, the HTC Polaris, HTC Sedna and the HTC Omni.
