I live in Summerwood as well. We enjoy it. I'll second the rec that you should stay away from the communities that are basically directly north of Fall Creek.
Fall Creek is larger than Summerwood and has more ameneties but I think their HOAs are higher- plus the additional cost if you want to join Redstone. I think Fall Creek is bigger than Eagle Springs too. Summerwood is a good size but smaller than the other 2. However, if you've got to commute out of the Upper East Side (if you live here, learn the terminology) Eagle Springs blows. You either have to take Will Clayton over to 59, or Atascocita to the BW or get over to W. Lake Houston and then onto the BW. Lakeshore is nice but you need to stay on the lake side (where the pool is located).
There's a lot going on out here:

There's also Duessen Park, Eisenhower Park, Sheldon SP, and a lot more green space in the very immediate vicinity which won't be developed because it's wetlands.
As for builders, Taylor Morrison built our house and my wife is their marketing director. They build in Fall Creek and have just returned to Eagle Springs & Summerwood.
I don't know the specifics on their plans here but if you email me at dfstarr at gmail dot com I'll pass it along to my wife and she'll help you out. She & her counterpart also run internet sales so she's very up to speed on everything.
Meritage is a good builder too but Taylor Morrison was voted the #1 builder in Houston by GHBA in 2010 & 2011. Taylor Morrison is also under contract to buy some raw land for a gated community immediately north of Summerwood on W. Lake Houston.
