It is very hard to predict the action of the school district. Let us accept that fact. Having said that, if you are overly concerned about it, you should stay away from those schools and go with the most safest school.
I have attended the meetings where the FUSD did their presentation. They have many proposal to solve this over loading issue, of which redrawing is one on the table . Time will tell what they would do. This is a problem they need to come up with a permanent solution. Every good elementary school is getting over loaded in Fremont. Warm Springs, Parkmont, Forest Park, and Ardenwood.
Good Luck with your decision making and give me a call to understand the micro dynamics.
I have heard from my niece, nephew and brother (all homeowners in Fremont) that what you say might be true; Fremont is rethinking how they draw the boundary again.
The reason is that Fremont has some outstanding schools and the school district feels its best to share the resources and make all schools in Fremont excellent schools, and apparently they have done a great job in doing so. I still think Fremont is an excellent area to move to due to the demographics of the area and how important the general public there think of education in general. When you have concerned parents and citizens, ,that's when a school district is an excellent one to move to, and Fremont is definitely one of the top choices around the Bay Area.
However, I agree with Pam and this is true about all school districts in all the U.S., the best t hing to do is for you to check with Fremont school district and get the most current scoop on the progress.
If you need more information, please feel free to give me a call.
