Never heard about that. Is there any detailed information, e.g. a comparison with old and new numbering?
Around 400 km of roads (mostly but not necessarily motorways or autostrassen) will be handed over by the cantons to the confederation, and will thus get a new Nxx/Axx number (on official documents all are designated with an N, on everyday life 1st and 2nd class roads are called A).
Here a list:
http://www.admin.ch/ch/d/gg/pc/documents/2262/Netzbeschluss_2012-12-10_de.pdf
For each setion is shown its class:
1st: motorway
2nd: autostrasse (like the A13 San Bernardino)
3rd: normal road (with flat junctions, but the fewest of them as reasonnable)
Note that each national road can be of different classes on different parts, but that only the 1st and 2nd levels will have a number in a red diamond.
Note also that the N2/A2 between Altdorf and Göschenen is 2nd class (as it is the Gotthard tunnel, obviously), and that the Gotthard pass road is also part of the N2 (as 3rd class), so between Göschenen and Airolo there are two roads called N2, the pass and the tunnel.
The list of all numbered roads (only for administrative purposes, no sign carries numbers above 30) can be found here:

Have they decided what to do in regard of renovation works of the San Gottardo tunnel?
Most of the federal council want second tunnel (the left parties oppose it), and I'm not aware of any alternative plan if the second tunnel is rejected by voters (he referendum will likely next year). I really don't know if voters will approve or reject it, but it's sure that it is the last chance to double it before 2050. I think the opponents will prevail by a few points at the referendum, but who knows? What is sure is that Socialist, Green and Green Liberal parties voters (around one third of the electorate) will massively vote against the second tunnel, but also many citizens usually following the other political parties might not follow the ideas of their parties for one time. Partly because for example Swiss-French don't need this tunnel so they might choose to keep its money for other projects (maybe in the Romandie), partly because everyone knows that the EU will soon ask for a 2+2 tunnel, so that the referendum will also be a decision in favour or against the Alpen-Initiative, and thus the rail transport. And as Swiss citizens rarely oppose rail projects, they might oppose the road tunnel for that reason. But really...who knows? Some surveys says that the second tunnel would be approved, but people can still change their mind when they have to write "yes" or "no" on the paper, the day of the referendum.
If the second tunnel is rejected, the tunnel would be closed during the winter, with the pass road kept open as much as possible and two separate RoLa/RoRo train services, on the old rail tunnel for cars and motorbikes and in the new rail tunnel for the trucks. I don't know where buses would go.
