What is the expected revenue for each segment (product and services) for Q2, and what is the expected mix? 
a, we're seeing strength continuing. One, obviously, they're past most wave most of the wave. So we see them continue strong. And two is, I think there's also they have China fabs that concerns around some of the new export controls that are being talked about in Washington. So we continue to see the China fabs continuing to invest as well as they're trying they're making both technology and capacity investments for a lot of the other fabs that are more related around technology investments, especially in the memory space. So we're still seeing strength in China, and we expect that to continue, especially while the pause is going on. The range on WFEs, what we're seeing from different pundits is basically, at best, it's flat and the worst not at the worst, but a lot of the estimates are single-digit decline.
And for the sake of planning, obviously, we do for the next quarter guidance, we're not looking at WFE numbers, we're looking at real orders and the situations around those. But as part of the range of where WFE could end up, like I said, a single-digit decline off of 2019 to flat. And then we don't really plan around any other scenarios that are more extreme than that, but of course, we have plans in place for when those do happen. So that I think that those are reasonable expectations, especially since the WFE has been somewhat, not immune, but less affected through at least the first half of the year under the belt. So we'll have to see what happens in the second half.

And the next question will be from Dick Ryan with Doherty. Please go ahead.
Dick Ryan -- Doherty -- Analyst
Thank you. So Jim, one of your longer-term goals has been to increase contributions from other key customers. Has the current environment shifted any of that potential sorts of market share gains, your ways, or is it still too early to tell on that?
Jim Scholhamer -- Chief Executive Officer
No. To date, especially our effort to grow, as you're right, our effort to grow, like 1/3 customer at 10% reporting, those that continues to go very well. We've done some we've had a series of very nice wins with one of the OEMs who's not in our top two. So that, we continue to see a lot of success in that. And a lot of those are projects and products that are coming out in next year, and those tend to continue regardless of what's happening in the moment. Those are the new product lineups. So we continue to see great successes in winning some programs and projects in that space. And so to date, we haven't seen any impact on our road map to as we expand our share.
Dick Ryan -- Doherty -- Analyst
Okay. And I heard the guidance for Q2, but did you I may have missed it, but did you talk about what your expectations are for each of the segments, the product and services for Q2, kind of the mix?
Jim Scholhamer -- Chief Executive Officer
No. We didn't break out by product line. But I think, as you can see, the revenue is nearly flat than we're projecting, so you can expect a similar mix.

The next question is a follow-up from Quinn Bolton with Needham & Company. Please go ahead.
Charles -- Needham & Company -- Analyst
Hey thanks for taking my call. Regarding the some of the OEM shifting some volumes to your way in the first quarter, can you let us know whether those market share shifted? Are they permanent? Or do you think they will go back to the original supplier? I just wanted to understand how we understand there's ebbs and flows in terms of share dynamics. But what's already shipped to go away, would they go away or they will stay with you?
Jim Scholhamer -- Chief Executive Officer
Yes, sure. Yes, obviously, some of them are clearly temporary shifts just around the situation, but I think it'd be reasonable to expect that some of the shifts would continue based on continued uncertainty around supply chain and our strong performance that we've ha
