A lot of what could make Pi rock is software. The hardware is quite impressive in possibilities. Their is enough potential to go for years. A faster better Pi wouldn't make today's Pi without use. Faster means more power, more power means a bigger plug, or less USB sockets to cull power in the balance.
When more bang for the buck comes out, Pi classico will still do project homework, and decode 1080p 'get some glasses instead' mp4 vision. I'd love a bit of solarized, dithered, pixelation low power options.
