Intel: 'Most significant' tech announcement on deck

Intel is planning a press conference on Wednesday touting "its most significant technology announcement of the year."

Details aren't currently available, but that's some advance billing for a powwow in San Francisco. So what could Intel be announcing? Here are a few guesses:

1. An architecture to replace x86 going forward.
2. Plans to offer ARM chips.
3. A breakthrough in smartphone computing power.
4. Details about its 22 nanometer manufacturing plans. Intel mentioned that on its earnings conference call.

But those are just guesses. Play along in the talkbacks and speculate a bit ahead of Wednesday.
