The Qualcomm roadmap for the next few years has leaked out, putting a time frame on the chips they announced last February. According to the leak, we should expect dual-core LTE, HSPA, and HSPA+ chips clocked anywhere from 1.5 GHz to 1.7 GHz to be in the hands of manufacturers late in Q3 of this year, with the Adreno 225 GPU on board. Come Q3 of next year, we should see the budget version start to make it's way into phones and other connected devices, with a Adreno 305 GPU and a bit lower (1.0-1.2GHz) clock speeds.
The "big deal," and what many are waiting for, are the quad-core Krait systems, complete with an Adreno 320 to push out 1080p video at 60 fps, and clock speeds in the 2 GHz and up range. We won't get to see those until early 2013 though. Of course, this is all subject to change -- if there's anything we all have learned from leaks, it's that they often don't hold true. They will arrive when they arrive, and I think we will love them.
