MPEG-4 does provide more capacity. For example, an MPEG-2 stream typically runs at 3.7 Mbps for a standard definition signal, MPEG-4 is expected to reduce that to 2-2.5 Mbps. A couple years behind MPEG-4 is MPEG-7 which promises another improvement in compression. Hence more channels can be carried in the same bandwidth block. You can also expect another wholesale equipment changeout if MPEG-7 gets traction.
The downside is that more compression also causes a more prominent impact from errors. The idea is that if you keep the number of signal errors constant, MPEG-4 will exhibit a more significant errors (tiling, frame loss, etc.) than MPEG-2
There will likely be a couple of HD channels added to the Buckeye lineup probably early next year, no word yet on which ones. You could also expect that Buckeye will be offering digital simulcast (all of the current analog channels available in digital for digital subscribers). This will also be available the first part of next year.
