Is there a ETH 2.0 or is 2.0 just moving to POS?

when i got all into crypto i watched a ton of informative videos, but some of it went over head but i felt like i got the basics.

2.0 will bring shards which i think is the equivalent of multi chains etc.. or maybe not, but i recall Eth1 will live on a shard and all tx's will be in that single shard.

anyway, back to my main question is ETH, ETH or will there be a new token for 2.0?
