Re: Interview with Toshi Terada sounds good to me

When I spoke to Akira Watanabe (who is more senior than Terada san) when the E-P3 was launched, he rated the 12mm f/2.0 as equivalent to a 'high grade' Four Thirds lens, not Top Pro or Super High Grade (SHG), although he did add that the optical performance of the lens had exceeded expectations. Apart from the m.Zuiko 12-50 kit lens and the 60mm macro, none of Olympus' m.Zuiko lenses are sealed. This might be part of Watanabe san's reasoning. But optically there are no problems at all with the 12mm f/2.0, 45mm f/1.8, 75mm f/1.8 nor the 60mm f/2.8.

So I think you have hit the nail on the head - there are no high grade fast zooms from Olympus. Panasonic has produced some like the 12-35 f/2.8 and the 35-100 f/2.8, although these are a stop slower then their Zuiko equivalents.
