GTA IV sells 926,000 units first week in UK

Although we're going to have to wait until next month's NPD report for the US info, Chart-Track revealed that GTA IV sold 926,000 copies during its first week on sale in the UK. Gi.biz reports this means GTA IV has broken the "all format" record, while the "individual format" record still belongs to GTA: San Andreas with 677,000 units sold its first week on the PS2.

We previously had Chart-Track's estimates on GTA IV's first-day sales, but the official tally was 631,000 units. During the first week, 514,000 copies were sold for Xbox 360, while 413,000 sold for PS3 -- a 55/45 split. We really wish Take-Two would just give the global figure already.

Update: Yes, we know the math doesn't work (514k + 413k ≠ 926k), so we're guessing Chart-Track rounded up somewhere and rounded down somewhere else.
