Carmarthen Quins' Lee Williams is the sole survivor from that side, who started as 80-1 outsiders but went on to beat New Zealand, Samoa and Argentina en route to becoming World champions.
With 30 IRB Sevens tournaments behind him, Williams brings a wealth of experience with only Rhys Shellard having played more tournaments (35) on the international circuit.
Wales will line up in pool E in Moscow with two-time Melrose up winners Fiji, Tonga and Uruguay.
Pontypridd's Adam Thomas will lead the side, which finished seventh in this season's HSBC Sevens World Series.
World Cup selection has proved a double celebration for the Davies household. Only days after Jonathan was selected for a starting berth for the British & Irish Lions to take on Australia in the opening test, his younger brother James has made the trip to Russia.
Alex Webber's rapid rise also continues with his selection. Webber began last season in the SWALEC League with Ystrad Rhondda before being handed his chance by John in Dubai in the second round of the world series. Still only 21, he is the youngest member of the squad.
Cardiff duo Gareth Davies and Alex Walker have both returned to Sevens duty having spent time with the Blues last season, while Rhys Jones returns to the fray having recovered from an injury which kept him out of the last two rounds of the world series.
Llandovery speedster Chris Knight has also been included along with Llanelli's Craig Price, Carmarthen Quins' Jason Harries and Llandovery's Adam Warren, who has just returned from Wales' two Tests in Japan.
Wales Sevens World Cup squad: Adam Thomas (Pontypridd), Alex Webber (Ystrad Rhondda), Lee Williams (Carmarthen Quins), Gareth Davies (Cardiff), Chris Knight (Llandovery), Rhys Shellard (Pontypridd), James Davies (Carmarthen Davies), Alex Walker (Cardiff), Adam Warren (Llandovery), Craig Price (Llanelli), Jason Harries (Carmarthen Quins), Rhys Jones (Llandovery).
